Selecting paint for a car is a task that requires precision down to the micron shade. Even a slight deviation in color can make a freshly painted body part noticeable against the background of other parts. There are different reasons for choosing car paint: from local repairs after scratches to complete repainting of the car. But regardless of the scale of work, there is one main rule - the color must match 100%.

In this article we will analyze all the current methods for selecting paint: from using the factory color code to modern computer tinting systems. You will learn where to look for information about the original shade of your car, what tools will help you avoid mistakes, and why even professionals sometimes make mistakes. And also - Which paint brands give the most consistent results? and how to check the quality of the selection before application.

1. Where to find the car color code: 5 places on the body and in documents

The factory color code is a unique shade identifier that the manufacturer assigns to each model. It can consist of letters, numbers or a combination of both (for example, B5B for Volkswagen or 3002 for BMW). Knowing this code simplifies the selection of paint in 90% of cases, but finding it is not always easy.

This is where the color code usually hides:

  • 📄 Vin code (VIN) - not the code itself, but data on it in the manufacturer’s database (more details in the next section).
  • 🚗 Body plate - most often located on the driver's door pillar, under the hood or in the trunk. Look for a sticker with inscriptions Color Code, Farbe (for German cars) or Peinture (for French).
  • 📋 Service book - in the technical data section or on the last page.
  • 🔧 Spare wheel or niche under it - some manufacturers (for example, Toyota) duplicate code there.
  • 💻 Electronic databases - if there are no physical tags, the code can be found by VIN through services like PaintRef or Autocolorlibrary.

Important: on cars after 2010, the color code may be two-layer (for example, B5B/M3), where the first part indicates the base color, and the second - the type of varnish (matte, metallic, pearl). If you ignore the second element, the shade will be different!

2. How to find out the color of a car by VIN code: step-by-step instructions

The VIN code is a “passport” of a car, which contains information about the make, model, year of manufacture and, often, body color. However Not all manufacturers encode color in the VIN: for example, Mercedes-Benz and Audi this information is available, but Kia or Hyundai - no. To check whether you can find out the shade by your car's VIN, follow the algorithm:

1. Find the VIN (on the windshield, in the vehicle title, or on a plate under the hood)

2. Enter it into the database PaintRef.com or VinDecoderz.com

3. Check the "Exterior Color" or "Paint Code" section

4. Compare the found code with the mark on the body (if any)

5. Specify the type of paint (acrylic, metallic, pearl) -->

Decryption example: for Volkswagen Golf 2018 with VIN WVWZZZAUZJW123456 bases will give a color code LH7W — this is "Deep Black Pearl" (deep black mother-of-pearl). But if the database says N/A or "Data not available", which means the color is not determined by the VIN - look for it on the body.

⚠️ Attention: some online services show outdated data for cars after restyling. For example, Skoda Octavia A 2020 model may appear in the database with a color code from a 2018 model. Always double check the information on the physical tags on the car!

Car make Does the VIN contain a color code? Where to look alternatively
BMW, Mercedes, Audi Yes (in 90% of cases) Sign on the door post
Toyota, Lexus Partially (only for models before 2015) Under the hood or in the trunk
Kia, Hyundai, Renault No Service book or sticker on the body
Volkswagen, Skoda Yes, but only base color (no varnish type) Additional code on the plate (for example, B5B/M3)

3. Computer paint selection: how spectrophotometers work

If the color code is lost or you doubt its relevance (for example, the car has already been repainted), they come to the rescue spectrophotometers — devices that analyze shade with nanometer accuracy. They are used in professional car services and cost from 50,000 rubles, but the result justifies the investment.

How the selection works:

  1. The technician cleans an area of the body (usually the fender or hood) of dirt and wax.
  2. The device scans the surface at 3–5 points (to take into account possible color variations).
  3. The program compares the data with the shade database and provides a recipe for tinting.
  4. The paint is mixed using special equipment (for example, a Mixit or Spies Hecker).

🔍 Advantages of the method: accuracy up to 98%, taking into account paint fading in the sun, the ability to select for metallics and chameleons.
⚠️ Cons: high cost (from 3,000 rubles per selection), dependence on the qualifications of the master.

💡

If you are painting only one part (for example, a bumper), ask the specialist to do a test spray on cardboard or an old spare part. This way you can see how the paint looks in different lighting and avoid surprises after painting.

4. Top 5 car paint brands: which ones to choose for accurate selection

Not all paints are equally stable. Cheap analogues can change shade after a year, while original ones will retain color even after 10 years of use. Here is a rating of brands that professionals recommend for accurate selection:

  • 🥇 PPG (series Deltacron) - leader in accuracy for European and American cars. Used on conveyors BMW and Porsche.
  • 🥈 Spies Hecker (ruler Permahyd) - the best choice for metallics and pearls. The price is above average, but the result is predictable.
  • 🥉 Sikkens (series Autocryl) — optimal price/quality ratio. Suitable for Asian brands (Toyota, Mazda).
  • 4️⃣ Mobihel (ruler ColorSystem) - a budget option for local repairs. The accuracy is worse, but for small areas it will do.
  • 5️⃣ DuPont (series Chromabase) — premium class for rare shades (for example, “chameleons”). Used in tuning studios.

⚠️ Attention: Even top brands have “failures” in some colors. For example, PPG ideal for Mercedes, but may give an error of Nissan with mother of pearl. Always check with your supplier to see if they have an up-to-date formula for your color code.

Why do cheap paints change color?

Budget paints often use unstable pigments that react to UV rays. After 1–2 years, this shade may turn green or blue, especially in the south of Russia, where the sun is more active.

5. How to avoid mistakes when selecting: 7 life hacks from painters

Even with a color code and a spectrophotometer you can make mistakes. Here's what experts with 10 years of experience advise:

  1. Check the paint in daylight. Artificial lighting (especially LED) distorts the color. It is best to evaluate color outside in cloudy weather.
  2. Consider the age of the car. Paint fades by 5–15% in 5 years. If the car is more than 7 years old, add 2-3% brightener to the recipe.
  3. Test on an unnecessary part. For example, on the inside of a bumper or an old door. This way you can see how the paint lays down and dries.
  4. Don't skimp on varnish. Cheap varnish can turn yellow and ruin even a perfectly chosen color.
  5. Check the paint lot. From the same manufacturer, the shade may differ in different batches. Compare lot numbers on jars.
  6. Use original solvents. An unsuitable solvent changes the viscosity and, as a result, the shade after drying.
  7. Trust only certified tinting centers. Garage shops often thin the paint to save money.

💡 Secret from the pros: if you are painting a plastic bumper, add 5-10% to the paint plasticizer (for example, PPG DX330). This will prevent cracking and make the color more saturated.

6. Selecting paint for metallic and pearl: why is it more difficult?

Paints with a metallic or pearlescent effect contain microparticles of aluminum or mica, which create color shifts at different angles. Because of this, choosing such a shade is 2 times more difficult than regular acrylic. Here are the key details:

  • 🔄 Spray direction. Metallic is applied in 2-3 layers with cross spraying (the first layer is horizontal, the second is vertical). If the technology is violated, the overflow will be uneven.
  • 🌈 Particle size. Cheap paints have larger particles, so the glitter effect looks rough. Original paints (eg. Spies Hecker ColorSurf) give smooth transitions.
  • 🎨 Base coat + varnish. Mother-of-pearl requires mandatory varnish coating (at least 2 layers), otherwise the particles will “sink” in the paint and the effect will disappear.

⚠️ Attention: if you are painting only part of the part (for example, half a wing), do not use metallic! The border between the old and new coating will be visible due to the difference in overflow. In such cases, it is better to paint the entire part or use acrylic.

💡

For metallics and pearls, be sure to use original pigments from the paint manufacturer. Substitutes (even from the same brand) can give a green or blue undertone that will appear after a year.

7. What to do if the paint doesn’t match: correcting mistakes

Even professionals make mistakes. If after painting you notice that the color is different, do not panic - the situation can be corrected. Here is the algorithm of actions:

  1. Check out the difference. If the shade differs slightly (by 1-2 tones), you can apply a correction layer with the addition of pigment.
  2. Check the technology. Often the problem is not with the paint, but with improper drying or the number of layers. For example, a metallic without varnish will look dull.
  3. Use a transition. For large parts (hood, roof), the master can make a smooth color transition using shading.
  4. Repaint completely. If the difference is critical, you will have to paint the entire part or even adjacent elements (for example, both doors).

📌 Important: if the paint turns out to be darker than the original, it can be lightened by adding white pigment (no more than 5%). If it’s lighter, you’ll have to repaint it, since it’s almost impossible to darken it without changing the texture.

💡

If you painted the car yourself and got the color wrong, don't try to fix it on top of the old coat! Remove the paint with a sander (P800-P1000 grit) and start again. Otherwise, the new layer will lie unevenly, and the problem will worsen.

FAQ: Answers to frequently asked questions

Is it possible to choose paint based on a photograph?

Technically yes, but the accuracy will be low. The color in a photo depends on the lighting, camera settings, and even the shooting angle. Professionals use photographs only for preliminary assessment, and make the final recipe based on a physical sample or code.

How much does it cost to select paint at a car service?

The cost depends on the method:

  • By color code: 500–1,500 rubles (if the code is known).
  • Computer selection: 2,000–5,000 rubles.
  • Manual selection (tinting): from 3,000 rubles + cost of test samples.

In the regions, prices are 20–30% lower than in Moscow.

Can I mix the paint myself according to the code?

Theoretically, it is possible if you have professional equipment (scales accurate to 0.1 grams, mixer, pigment bases). But in practice, without experience, you risk getting an uneven shade or sediment in the jar. It is better to order ready-made paint from a tinting center.

Why is the paint on the bumper different from the body color?

There are several reasons:

  • The bumper is made of plastic, which requires a special primer (otherwise the paint will adhere differently).
  • Plastic and metal reflect light differently, so even the same paint can look different.
  • The bumper could have been painted separately, and the master did not take into account the fading of the main color.

Solution: use elastic paint for plastic (eg PPG Flex) and apply it in 3 layers with intermediate drying.

How to check the quality of the selection before painting?

Do a test spray on:

  • Cardboard (to evaluate the shade).
  • Steel plate (to check shine).
  • Old bumper (to see how the paint adheres to the plastic).

Compare in daylight and from different angles. If the difference is noticeable, adjust the recipe.
