Local auto body repairs or complete car repaints always start with one critical question: how to get the perfect color? Visually determining the shade “by eye” almost never gives the desired result, since modern factory enamels contain complex pigment compositions. That's why car paint by code is the only reliable way to restore the factory appearance of the car.
Manufacturers use special digital or alphanumeric designations that correspond to a specific mixture recipe. Knowing this code, colorists can recreate the color with microscopic precision, taking into account even the nuances of fading or the specifics of metallized particles. Ignoring this parameter often results in the painted part being noticeably different from the rest of the body.
In this article, we will look in detail at where to look for markings on various car brands, how to read the data correctly, and why ordering professional tinting is preferable to buying ready-made aerosols. Understanding these processes will save you money and stress while guaranteeing an aesthetically pleasing result.
Where to look for the paint code on a car
The first thing you need to do before ordering materials is to find the nameplate or sticker with technical information. The location of this element is not standardized and depends on the manufacturer, year of manufacture and even the specific model. Most often VIN code and a nameplate with color are located in the engine compartment or on the body pillars.
Please note that on modern vehicles, information may be duplicated in several places. If you don’t find the sign right away, don’t rush to conclusions. Sometimes it is hidden under decorative trims or behind plastic plugs, especially in the area of the trunk or glove compartment lock.
Owners of used cars should be especially careful. If the car was repainted by previous owners, the sticker may have been removed or painted over. In such cases, searching for a paint code becomes more difficult, but is possible through special databases or catalogs.
- 🚗 European cars (VAG, BMW, Mercedes): Most often, the plate is located on the B-pillar (driver's side) or in the spare wheel well in the trunk.
- 🇯🇵 Japanese brands (Toyota, Honda, Nissan): look for markings in the engine compartment, on the shock absorber “glass” or on the central door pillar.
- 🇺🇸 American cars: Often they use a sticker with a list of all option codes, including color, which is affixed to the door or in the door opening on the driver's side.
- 🇰🇷 Korean manufacturers: The nameplate is usually placed under the hood, next to the engine shield or on the side member.
If the paint code sticker has worn off or is missing, try to find the VIN code (17 characters) and contact an authorized dealer - he will be able to tell you the factory color code based on the base.
Remember that the paint code is not always the vehicle's VIN number. This is a separate parameter that can be designated as C, Paint, Farbe or simply be highlighted in font color on a common sign.
Decoding the markings of different manufacturers
Each automaker uses its own coding system, and it is easy for a beginner to get confused in the abbreviations. For example, the group Volkswagen the code usually consists of 3-4 characters (for example, LY7C for gray color), and for BMW it can be a three-digit number in the format 275 or A96. Understanding the manufacturer’s logic helps you navigate catalogs faster.
Japanese brands such as Toyota or Lexus, the code often begins with the prefix C/TR, where the first part is the exterior color, and the second is the interior color. It is important not to confuse these values, since you will not need the salon code for painting. U Honda the code may be indicated twice: one for the body, the other for plastic elements that fade differently over time.
Complex encoding cases
For some manufacturers (such as Ford or Mazda), the color code may be part of a long string of letters and numbers with no obvious separation. In such cases, it is better to take a photo of the entire sign and send the photo to a professional colorist for interpretation.
Particular attention should be paid to multilayer coatings. If your car is metallic or pearlescent, the code will indicate the base pigment, but the application technique may require additional components. Sometimes a suffix is added to the main code indicating the type of varnish or the presence of an effect.
| Car make | Where to look for the code | Code format | Example |
|---|---|---|---|
| Volkswagen, Audi, Skoda | Body pillar, trunk, service book | 3-4 characters (letters and numbers) | LY7C, Z5Z5 |
| BMW | Under the hood, pillar, fuel filler flap | 3 numbers (sometimes with a letter) | 475, A52 |
| Mercedes-Benz | Body pillar, radiator frame | 3 digits | 775, 199 |
| Toyota, Lexus | Body pillar, engine compartment plate | 3 characters (numbers or letters) | 040, 1G3 |
| Ford | Driver's door pillar | 2 characters (in the Exterior Paint column) | YZ, J7 |
It is important to note that the same visual color can have completely different codes from different manufacturers. White color BMW (Alpine White) is one composition, and Toyota (Super White) is completely different, so you cannot mix paints by name, only by code.
Process of selection and computer tinting
Once you have found the code, the selection process begins. Simply mixing the components according to the recipe is often not enough, since the factory paint on your car has already been exposed to ultraviolet radiation and reagents. Computer tinting allows you to take these changes into account and create a mixture that will be indistinguishable from the original.
The process is as follows: a specialist enters the paint code into the program, which produces a basic recipe. Then, using a high-precision scale, he mixes the pigments. However, the work doesn't end there. An experienced colorist always does a “painting” - he applies a test layer to a metal plate, dries it and compares it with a sample of the car body under different lighting.
☑️ Checking paint readiness
Why is this so important? Because even within the same code there can be small manufacturing tolerances. In addition, if the vehicle has previously been repainted with non-original paint, the factory code will no longer match the current color. In such cases, complex manual tone adjustment is required.
Modern tinting systems make it possible to take into account even the size of aluminum particles in metallics, which directly affects the brightness and direction of shine. Usage spectrophotometer helps to read the color directly from the body if the code is lost or the paint is heavily faded, creating a digital color profile.
Ready-made spray paint versus professional paint
Many car enthusiasts consider buying ready-made aerosol cans as a way to save money. Indeed, there are services that refill cans with any paint according to the code. However, there are significant differences between this solution and professional painting in a chamber.
Finished paint in a can often has a standard viscosity and may not contain the necessary components for a particular application technology (for example, the correct solvent for a certain air temperature). Professional enamel, prepared in a paint shop, is diluted specifically for the conditions in which the repair will be carried out.
⚠️ Attention: Cheap "to code" aerosol paints often have low pigment content and an unstable spray pattern. This can lead to shagreen, streaks and rapid fading of the repaired area.
If you plan to paint a small scratch or plastic item, a quality spray can of matched paint can be a great solution. But for painting large body elements, such as a fender or door, it is better to use a professional spray gun and two-component systems (base + hardener), which ensure a chemical reaction and durability of the coating.
In addition, in a spray can it is impossible to use the correct sequence of application of layers (primer, base, varnish) while observing interlayer drying as is done under stationary conditions. Aerosol varnish is often less resistant to mechanical stress than professional two-component varnish.
Features of working with metallics and mother-of-pearls
Paints with effects metallic and mother of pearl require a special approach. Unlike plain enamels, where the color depends only on the pigment, the location of the aluminum or mica particles is critical here. Incorrect application can change the shade by several tones, making the piece lighter or darker.
When working with such materials, the paint code specifies only the base, but the final appearance depends on the application technique. The pressure in the spray gun, the distance to the surface, the speed of the hand movement and even the number of layers are important. An overdried layer will cause the metal particles to lie flat, which will give a dark shade, while an underdried layer will, on the contrary, give a light shade.
Another feature is the mandatory application of clear varnish. The metallic base layer has no gloss or protection, it looks matte and rough. Only after varnishing does the depth of color and the iridescence effect appear. Skipping this step or using low-quality varnish will ruin the entire result.
- ✨ Torch direction: When painting metallics, the final “foggy” layer is applied from a greater distance to even out the orientation of the particles.
- ⏱ Drying time: It is necessary to maintain precise intervals between base layers (usually 10-15 minutes) so that the solvent has time to evaporate, but the layer remains sticky.
- 🌡 Temperature: in a cold room, metal powder can float or sink, changing color, so painting is carried out at strictly +20°C.
It is also worth remembering the phenomenon of the “flop effect”. This is a change in apparent color depending on the viewing angle. When selecting paint according to a code, colorists must check this parameter so that when viewed from a right angle, the color matches one standard, and when viewed from an acute angle, it matches another.
Common mistakes when ordering and painting
The most common mistake is confusion between the body code and the interior code. As mentioned earlier, there can be multiple meanings on a plate. If you dictate the interior code, you will receive a completely different paint color that will contrast with the body.
The second mistake is ignoring the age of the car. The paint fades over time. If you order paint code for a 10-year-old car, the new part may look brighter and fresher than the rest. In such cases, professionals often use a “transition” technique (blend) to smooth out the difference, or specifically lighten/darken the tone.
Always check the paint code from multiple sources (plate, documents, VIN databases) before placing an order. One wrong number will result in the purchase of the wrong material.
The third mistake is saving on materials. Buying cheap solvents or hardeners can ruin even paint that is perfectly matched to the code. It may not dry, become cloudy, or blister a week after repair. The chemistry must be compatible with the base.
⚠️ Attention: Never mix paints from different manufacturers, even if the codes are the same. Chemical bases (acrylic, urethane, nitro) can enter into unpredictable reactions, curling up right in the jar or on the car body.
Adhesion is also often forgotten. Before applying the selected enamel, the surface must be properly prepared: degreased, matted and covered with primer. Applying paint to smooth plastic or old glossy varnish without preparation will result in the new paint simply peeling off.
Can I find the paint code by VIN online?
Yes, there are many services and sites that allow you to find out the paint code by VIN number. However, the databases are not always complete and may contain errors. The most reliable way is to physically search for the plate on the car or ask an official dealer of the brand.
How long does selected paint last?
In a sealed factory container, paint can be stored for several years. If the can has been opened or the paint has been mixed with a hardener, the lifespan is drastically reduced. It is better to use the finished mixture within 6-12 months, provided it is sealed, but ideal quality is maintained in the first months.
Why is the paint code different on a car?
There may be several reasons: burnout of the old coating, previous poor-quality repairs, an error in reading the code or a manufacturing tolerance. In such cases, manual adjustment of the tone by a colorist is required immediately before painting.
Do I need to varnish the paint if the color is not metallic?
Most modern automotive enamels (two-component acrylic) already contain gloss and do not require varnishing unless specified in the instructions. However, many artists still recommend applying varnish for added protection and depth of color, especially on darker tones.
