Feeling Blue? The Ultimate Guide to Blue Car Colour Codes
Your Quick Guide to Blue Car Colour Codes
If you have ever searched for blue car colour codes and ended up more confused than when you started, you are not alone. The right code is the difference between a repair that blends perfectly and one that stands out for all the wrong reasons.
Here is a quick reference to the most common blue car colour codes by manufacturer:
| Manufacturer | Colour Name | OEM Code | Finish Type |
|---|---|---|---|
| Honda | Aegean Blue | B593M | Metallic / Pearl |
| Honda / Acura | Indigo Blue | B502P | Metallic |
| GM / Cadillac | Opulent Blue | WA705U | Metallic |
| GM / Chevrolet | Admiral Blue | WA705U (GTR) | Metallic |
| Ford (Fleet / Special Order) | Blue | WT8049 | Solid |
These are OEM (original equipment manufacturer) codes, meaning they come directly from the vehicle manufacturer and are the most reliable starting point for any colour match. Cross-reference codes from paint manufacturers like PPG/Ditzler, RM/BASF, and DuPont are also available for each, which is useful when sourcing paint from a third-party supplier.
To find your specific code, check the paint code placard on your vehicle, typically located on the door jamb or in the engine bay, and use that code alongside your VIN (vehicle identification number) for the most accurate match. For a step-by-step guide on locating your code, see How To Find Your Paint Code.
Getting the wrong blue is one of the most common and frustrating mistakes in vehicle refinishing. Blue is one of the most varied colour families in automotive paint, spanning dozens of shades, finishes, and formulations across manufacturers, and even the same code can vary slightly depending on which factory built your car.
I'm James Maranis, owner of Eastern Auto Paints, and with over 30 years in the coatings industry, I have seen how a misunderstood blue car colour code can turn a straightforward touch-up into a costly rework. In this guide, I will walk you through how these codes work, how to decode them by manufacturer, and how to get an exact match the first time.
Key Takeaways
- Locate the OEM Code First: Always find the physical paint placard on your vehicle rather than relying on digital screens or promotional names.
- Understand the Finish: Blue paints vary significantly between solid, metallic, and pearl finishes, which change how light reflects off the panel.
- Watch for Factory Variations: Manufacturers like Honda use plant suffixes in their codes because slight differences exist between different assembly plants.
- Use Professional Matching Services: For the best results, use our advanced Colour Matching Services to account for paint fading and environmental wear.
- Always Consult the TDS: Mixing ratios, drying times, and application techniques vary by product, so always refer to the manufacturer's technical data sheet.
At Eastern Auto Paints, we do not believe in close enough when it comes to your vehicle's finish. Whether you are a professional spray painter in a busy Melbourne panel shop or a dedicated restorer working on a classic project in your home garage, we are here to provide the precise products, authentic materials, and expert guidance you need to get the job done right.
We specialise in helping you navigate the complex world of automotive coatings, ensuring you walk away with a perfect match and the confidence to apply it.
Why This Issue Should Not Be Ignored
Ignoring a slight mismatch in your vehicle's blue paint might seem tempting, but it can lead to significant aesthetic and financial headaches down the road. Blue is a highly complex colour family. Because of how light interacts with blue pigments, even a tiny variation in the shade or metallic flake size will be immediately obvious under direct sunlight.
A mismatched panel does more than just look unsightly. It directly impacts the resale value of your vehicle. Prospective buyers and professional inspectors easily spot inconsistent paintwork, which often signals past accident damage or low-quality repairs.
Furthermore, automotive paint does not just provide visual appeal; it serves as a critical protective barrier against environmental hazards. Failing to address chips or scratches promptly can lead to moisture penetration and rust.
When you perform a repair, achieving a seamless transition requires precise panel blending. If you start with an incorrect paint formulation, blending becomes nearly impossible, resulting in a patchy, uneven finish.
To understand how to avoid these common refinishing traps and achieve a professional result, refer to our comprehensive Car Paint Colour Matching Guide.
Common Symptoms, Challenges, or Questions About Blue Car Colour Codes
When searching for the perfect blue, many vehicle owners face a confusing array of names and codes. A challenge is that a single physical paint formulation can be marketed under several completely different promotional names.
For example, the General Motors formulation known by the Fisher paint code WA705U has been marketed as Opulent Blue on Cadillacs, Admiral Blue on Chevrolet Corvettes, and Blue Abyss, Ultra Blue, or Xenon Blue on other models across different years. If you shop for paint using only the marketing name, you run a high risk of choosing the wrong product.
Another common challenge is distinguishing between solid, metallic, and pearl finishes. A solid blue paint uses flat pigments with no reflective particles. Metallic blues contain tiny embedded aluminium flakes that catch the light, while pearl blues utilise iridescent mica particles to create a strong, colour-shifting effect.
Additionally, paint formulations degrade over time due to UV exposure and weather conditions, meaning the paint on your car today might not perfectly match the day it rolled off the assembly line. To explore these complexities in detail, see our Colour Matching Complete Guide.
Decoding Manufacturer Formats for Blue Car Colour Codes
Every automotive manufacturer has its own unique system for structuring paint codes. Understanding these formats is key to unlocking the exact formulation for your vehicle.
- Ford: Standard production Ford codes typically begin with the letter M, followed by a series of numbers and letters. However, Ford also uses special-order prefixes. Codes starting with WT or MX indicate special-order or fleet paints, which are commonly used for commercial vehicles, utility fleets, or municipal services. A classic example is WT8049, a durable fleet blue that has been utilised across multiple decades. Short codes like W8049H are sometimes used in databases, but they may not be unique, making the longer manufacturing code far more reliable.
- General Motors (GM): GM uses a comprehensive coding system often referred to as the Fisher paint code. These codes typically start with WA, followed by a four-digit alphanumeric sequence, such as WA705U. GM vehicles may also display a shorter three-digit option code, like GTR, on the compliance plate. For precise tracking and ordering, the longer WA code is always the safest choice.
- Honda and Acura: Honda paint codes follow a highly structured prefix system. The code starts with a letter denoting the generic colour family, where B stands for blue, PB denotes pale blue, and BG represents blue-green. This is followed by a numbers-and-letters sequence, such as B593M for Aegean Blue.
Crucially, Honda codes often include a plant suffix, such as -E, -H, or -S. Since the 1990s, slight differences in paint formulations have existed between different assembly plants.
To find the exact plant variation, you must check the 11th digit of your vehicle's VIN, which identifies the manufacturing plant. Matching this suffix is vital for an exact colour match. For a clear breakdown of how to read these manufacturer-specific systems, check out How To Understand Paint Colour Matching In 3 Easy Steps.
Identifying Solid, Metallic, and Pearl Blue Car Colour Codes
The visual characteristics of your blue paint depend entirely on the type of finish formulated by the manufacturer. Identifying which finish your code represents is crucial for choosing the correct application technique.
| Finish Type | Key Characteristics | Light Reflection | Common Examples |
|---|---|---|---|
| Solid Blue | Single-tonal, flat pigment with no reflective additives. | Reflects light evenly across the surface. | Ford Fleet Blue (WT8049) |
| Metallic Blue | Contains tiny embedded aluminium flakes. | Sparkles and glitters under direct light. | GM Opulent Blue (WA705U) |
| Pearl Blue | Utilises iridescent mica or ceramic particles. | Creates a deep, multi-layered, colour-shifting effect. | Honda Aegean Blue Pearl (B593M) |
Because metallic and pearl finishes rely on the precise suspension of reflective particles within the paint film, achieving an invisible repair requires professional care. To learn more about selecting the right products for these complex finishes, read our guide on Touch Up Paint Colour Match.
Cross-Referencing Paint Codes Across Manufacturers
When you buy paint for a repair, you will often find that paint manufacturers use their own internal codes to represent OEM formulations. These are known as cross-reference codes.
Major global paint manufacturers, including PPG (formerly Ditzler), RM/BASF, and DuPont, maintain massive databases that map OEM codes to their own mixing formulas. For example, Honda's Aegean Blue (B593M) cross-references to PPG code 935766 and RM/BASF code 905154. Meanwhile, the classic Ford fleet blue (WT8049) cross-references to PPG code 13588 and DuPont code 7250.
These cross-reference codes are incredibly useful because they allow paint specialists to look up the exact chemical recipe required to mix your paint using modern tinting systems. Databases such as PaintRef.com and Color-Hex.com are excellent resources for researching these historical connections.
To understand how paint technicians use these cross-references to blend custom batches, read our article on Mixing Matching Car Paint Colours.
What a Personalised Experience Actually Looks Like
At Eastern Auto Paints, we know that matching paint is not as simple as reading a code off a computer screen. Digital displays operate in the RGB or Hex colour spaces, which are designed for glowing screens, not physical pigments.
Physical automotive paint relies on complex chemistry, actual metal flakes, and real-world light reflection. That is why we provide a personalised, trade-focused experience to ensure you get a perfect match.
When you bring your vehicle or a panel to our Bayswater head office or our Dandenong South trade showroom, we do not just rely on the factory code. We use advanced colour-matching technology, including state-of-the-art spectrophotometers.
These digital hand-held devices physically scan your paintwork, measuring how light reflects off the surface to analyse the exact level of paint fading and UV wear.
Our team of experienced specialists then compares this data against thousands of saved formulations in our database. We can adjust the mix to account for years of weathering, giving you a custom-blended paint that matches your car as it looks today, not just how it looked when it left the factory.
This level of precision is why Melbourne's leading panel beaters and spray painters trust us for trade-level accuracy. To see how our advanced tools can assist with your next project, read about the Best Colour Matching Services For 2026.

Frequently Asked Questions About Blue Car Paint
How do I choose between 1K and 2K products for a blue car paint job?
Choosing between single-pack (1K) and two-pack (2K) products depends entirely on the requirements of your specific job, your workshop environment, and your equipment. A 1K product is a single-component paint that dries through solvent evaporation, making it straightforward to use for quick touch-ups or smaller panels. A 2K product relies on a chemical reaction between the paint and a hardener or activator to cure, creating a highly durable, chemical-resistant, and UV-stable finish. Because 2K coatings cure to a much harder film, they are the standard choice for professional commercial refinishing and high-wear areas, whereas 1K products are often preferred for simpler, fast-turnaround repairs.
How does the colour-matching process handle faded or weathered blue paint?
When a vehicle is exposed to sunlight and weather over several years, the paint pigments naturally degrade and fade, meaning the paint on the car no longer matches the original factory specification. To resolve this, we do not simply mix paint straight from the OEM code. Instead, we use advanced colour-matching technology, including digital spectrophotometers, to physically measure the faded paint on your panel. Our experienced colour-matching specialists then manually adjust the mixing formula, tinting the paint to match the current aged condition of your vehicle for a seamless blend.
What safety practices and PPE should I use when spraying blue automotive paint?
Working with automotive paints and solvents requires strict adherence to safety practices to protect your health. Because personal protective equipment (PPE) requirements vary significantly depending on the chemical composition of the product you are using, you must always consult the product's technical data sheet (TDS), safety data sheet (SDS), and relevant WorkSafe Victoria guidelines before starting. For example, spraying isocyanate-containing 2K paints requires specialised respiratory protection, such as an air-fed respirator, along with appropriate gloves and overalls, whereas water-based or 1K paints may have different requirements. Always ensure your workspace is highly ventilated and that you are using the exact safety equipment specified by the manufacturer.
Where can I find the exact technical specifications for mixing and applying my paint?
The only authoritative source for technical specifications, including mixing ratios, thinners, spray pressures, flash-off times, and curing temperatures, is the paint manufacturer's technical data sheet (TDS) or the product label. Because these specifications vary from product to product, you should never rely on general rules of thumb. If you need help sourcing the correct TDS or understanding the application guidelines for a product purchased from Eastern Auto Paints, our technical team is always available to assist you.
Why does the manufacturing plant code matter for my Honda or Acura blue paint?
Even though two vehicles may share the exact same base paint code, such as Aegean Blue (B593M), they may have been assembled at different factories around the world. Since the 1990s, minor variations in paint formulations, pigment batches, and application machinery have existed between different manufacturing plants. Honda and Acura account for this by adding a plant suffix to their codes, which corresponds to the 11th digit of your vehicle's VIN. Checking this suffix is essential to ensure that the metallic flake and shade variation perfectly match your specific vehicle.
