At first glance, it may seem that determining the color of a car is a trivial task that does not require any special knowledge or tools. However, in the professional body repair and insurance environment, the concept of “color” has a much deeper meaning, going far beyond simple visual perception. An owner may call his car white, but in the manufacturer's language it may be "Alpine White" with a pearlescent effect or "Glacier White" without any additives, and confusion here can lead to serious financial losses when painting.
Understanding the true color of a car is critical not only for painters, but also for ordinary car owners planning local chip repairs or purchasing body parts. Visual assessment often fails due to the characteristics of lighting, the degree of fading of the paintwork coating (LPC) and the presence of various pigment additives. That is why special identification is used for accurate identification. color codes, encrypted in nameplates.
In this article, we'll look at where to look for these codes, how to read manufacturers' catalogs, and why your "black" car may actually be dark blue or dark green depending on the angle of the light. We will also touch on the topic of paint aging and how time changes the original shade, making paint selection impossible without taking these factors into account.
Where to look for the factory color code on a car
The first and most important rule: never rely on a visual shade determination when ordering paint. Each car manufacturer places information plates or stickers in strictly defined places, which indicate the VIN number, production date and, most importantly for us, the body color code. The location of these plaques varies from brand to brand, and the search sometimes turns into a quest.
Most often, information is duplicated in several places. The main document is a service book or a sales contract, where the code can be written in letters. However, for painting work, it is the factory code that is required, which is often a combination of several letters and numbers. You can find it under the hood, on the body pillar or in the luggage compartment.
⚠️ Attention: Never use a color code found on body parts that may have been previously repainted. Look only for an original nameplate or sticker that has not been exposed to the elements.
For popular brands, the location of the codes is usually standardized, but may vary depending on the model year. For example, in the German car industry, plates are often located in the spare wheel well or on the inside of the gas tank cap. Japanese manufacturers prefer to place information on the driver's door pillar.
- 🚗 BMW: The engine compartment (on the glass or partition), sometimes duplicated in the trunk under the mat.
- 🚙 Mercedes-Benz: Driver's door pillar, engine compartment (on the radiator frame).
- 🚕 Audi / Volkswagen: In the trunk under the mat (sticker on the service book) or on the door pillar.
- 🚐 Toyota / Lexus: Driver's door pillar (lower part), engine compartment.
Explanation of symbols and structure of codes
After the plate is found, the owner is faced with the task of correctly interpreting the data indicated there. Nameplates contain a lot of information: tire pressure, permissible axle load, VIN code. The color code is usually highlighted separately and may be indicated by abbreviations like LB9A, 040 or NH-797P.
It is important to understand the structure of these notations. Often the code consists of a main part that determines the color, and an additional part that indicates the type of coating (metallic, mother-of-pearl, three-layer color). For example, some manufacturers have a code metallic may differ from the base color code by just one number or letter at the end. An error in one character will result in the store selling you a jar with a completely different shade.
For Japanese cars such as Nissan or Mazda, codes are often three-digit combinations where the first digit may indicate a color series. European concerns such as Renault or Peugeot, use alphanumeric notations that may not be obvious without consulting the catalog. In some cases, the plate may indicate a primer code or interior code, so it is important not to mix up the lines.
What to do if the code is erased?
If the factory sticker has become unusable and the code is not readable, you can try to find duplicate information in the service book or work orders from an authorized dealer. There are also online VIN code databases, but their accuracy is not always 100% guaranteed.
Below is a table with example codes for some common colors from different manufacturers to give you an idea of what they might look like visually:
| Manufacturer | Example code | Color name | Coverage type |
|---|---|---|---|
| BMW | 300 | Alpine White III | Enamel (Solid) |
| Toyota | 040 | Super White II | Enamel (Solid) |
| Mercedes | 775 | Obsidian Black | Metallic |
| Audi | LY9B | Tornado Red | Enamel (Solid) |
| Honda | NH731P | Crystal Black Pearl | Mother of pearl |
Differences between catalog and real colors
Even knowing the exact paint code, you cannot guarantee that the new body element will perfectly blend with the old one. This is due to the physical and chemical processes that occur with the paintwork throughout the life of the car. The factory color is a standard fixed at the moment the car leaves the assembly line, but reality makes its own adjustments.
The main enemy of color stability is ultraviolet radiation. Under the influence of the sun, the pigments in paint gradually break down or change their structure. Red and blue colors fade the fastest, becoming paler and less saturated. White colors may turn yellow, especially if they are old-style acrylic enamels, although modern “metallics” and “pearl” are more durable.
In addition, surface texture affects the perception of color. The glossy shine of a new varnish is different from the dullness of the old one, even if they are chemically identical. Oxidation of the top layer of varnish creates micro-roughness that scatters light differently. Therefore, during local repairs, craftsmen often recommend polishing the transition or even repainting the entire panel (for example, the entire door) to avoid the “patchwork” effect.
⚠️ Attention: Do not try to paint over a chip with a brush, choosing the color only according to the code on the new car. On a used car, the paint has already faded, and a fresh coat will stand out as a bright spot.
It is also worth considering the storage conditions of the car. Cars living under trees or in garages with poor ventilation may have specific stains from resin or reagents that change the local shade. In such cases, simple washing and polishing can restore the color, but sometimes deep cleaning with clay or abrasive compounds is required.
Features of complex colors: mother of pearl and chameleon
There are colors that are almost impossible to understand without professional equipment. We are talking about three-layer coatings, chameleon colors (shifting color) and complex mother-of-pearl. These paints use mica pigments that refract light at different angles, creating a play of shades. The same car may appear purple in one light and blue in another.
The technology for applying such colors is more complex and expensive. Typically the process consists of three stages: applying a base coat (often black or grey), applying a colored pearl coat and varnishing. When repairing such surfaces, it is critical to follow the technology and number of layers. If you put fewer layers of mother-of-pearl, the color will be “poorer” and darker than the original.
For such colors, the code on the plate is only half the success. Often a computer paint selection is required, where the colorist mixes the components, checking a fan and a sample taken directly from the car. Visual assessment plays a decisive role here, since spectral analysis may not take into account all the nuances of burnout.
- 💎 Mother of pearl: Contains mica particles, gives a deep glow, requires careful application.
- 🦎 Chameleon: Changes shade depending on the viewing angle, the most difficult type of coating to repair.
- 🌫️ Metallic: Contains aluminum powder, gives a characteristic shine, requires correct orientation of the particles when drying.
When buying a used car with a rare chameleon color, be sure to check the gaps between the parts. If they differ in shade, it means that the car was in an accident and was repainted in violation of technology.
The influence of age and use on shade
The age of the car is a factor that cannot be ignored. As already mentioned, paintwork ages. But there are other factors: mechanical damage, exposure to chemicals (reagents on the roads, bird droppings, tree resin) and the quality of previous repairs. All this forms the current “color” of the car in the eyes of the observer.
Particular attention should be paid to plastic elements. Bumpers, mirrors and moldings often fade differently than metal bodywork, even if they were originally painted the same color. Plastic has a different heat capacity and surface structure. Therefore, the difference in shade between the bumper and the fender is a normal situation for a car older than 3-5 years, and when selling it they often try to pass it off as a “factory feature”.
If you are planning to buy a body part from a disassembly shop, be guided not only by the color code, but also by the year of manufacture of the donor. A part from a car the same year as yours is more likely to match the degree of fading than a part from a newer or older car. Ideally, take the element from a car that was in the same operating conditions.
⚠️ Attention: When purchasing a color-matched part, always ask for a guarantee of a match. Many sellers are not responsible for discrepancies if the part is already installed on the vehicle.
It is also worth remembering about the “memory” of paint. Some modern enamels can repair micro-scratches under the influence of heat (self-healing varnish), but this does not apply to color changes. However, aggressive polishing can remove a layer of varnish and change the visual perception of color depth, making it duller.
☑️ Check the color before purchasing the part
Precision Tools and Techniques
When visual inspection and knowledge of the code are not enough, the big guns come into play - spectrophotometers and computer programs. These tools allow you to break down the color into its components and create a mixture recipe that is as close as possible to the current state of the body. This is especially true for complex colors and high mileage vehicles.
The spectrophotometer scans the surface and provides color data in various color spaces (Lab, LCh). Based on this data, the program selects a formula for mixing base pigments. However, even this method does not provide a 100% guarantee, since the device reads information from the surface, and not from the depth of the layer, where the pigment could change its properties.
For the home mechanic who wants to gain a deeper understanding of the color of his car, there are mobile apps and online catalogs. By entering the VIN or paint code, you can see a digital reconstruction of the factory shade. This helps you understand how much the color of your car has changed over the years.
The professional approach also includes "paints" - test samples that are applied to a metal plate and compared to the body under different lighting conditions. Only after making sure of the match does the master begin painting the part. Saving at this stage means getting a result that will hurt the eye.
The exact color code is just a starting point. The actual shade depends on the history of use, fading and repair technology, so computer selection and test colors are often necessary for an ideal result.
Is it possible to completely restore the factory color of an old car?
Completely is extremely difficult. Even if you use the original paint according to the code, the new layer will differ from the old faded paintwork. For an ideal result, it is often necessary to repaint the entire car or make a competent color transition to adjacent panels.
Why does the color code not match the color in the catalog?
The code indicates the paint recipe at the time of production. Over the years of use, pigments fade and the varnish becomes cloudy. In addition, in different years of production the same code could imply slightly different recipes.
How often does the protective coating need to be renewed to maintain color?
Wax coatings should be renewed every 2-3 months, ceramic coatings last from 1 to 3 years. Regular protection slows down fading and oxidation, keeping color vibrant longer.
Does washing affect color retention?
Yes, the use of aggressive chemicals and brushes in automatic car washes creates micro-scratches (cobwebs) that make the color dull. Hand washing with a quality shampoo is preferable to maintain color depth.
