Selecting paint for a car is a task that at first glance seems simple, but in fact requires precision down to the micron. An error in shade can cost not only aesthetics, but also money: repainting a part will cost 1.5–3 times more than choosing the right one the first time. In this article we will analyze professional methods (from factory codes to computer analysis), typical mistakes beginners and ways to save without loss of quality.

Many car owners believe that it is enough to name the make and model and the technician will find the right color himself. In practice, even one manufacturer has a shade Metallic Silver may vary depending on the year of manufacture, batch of paint and even the region of sale. For example, Toyota 1G3 (silver) for the European market is 8% darker than for the Asian market. And BMW some colors changed their recipe every 2 years - and this does not take into account the special shades for limited editions.

Today, paint selection is a symbiosis of chemistry, optics and digital technology. But even with modern equipment, the result depends on the experience of the master. We will tell you how professionals work, what tools they use, and why it is sometimes cheaper to order tinting in a specialized laboratory than to trust an β€œeye meter” in a garage service.

1. Factory codes: where to look and how to decipher them

The first and most reliable way is to use original paint code from the manufacturer. It is indicated in the technical documentation of the car and is duplicated on the body. Each brand has its own location of nameplates:

πŸ”Ή Audi/VW/Ε koda/Seat: Paint code consists of 2-3 characters (for example, LY7D or 9U9U) and is located on a plate in the trunk, under the hood or on the driver's door pillar.

πŸ”Ή Toyota/Lexus: look for a combination of type 1G3 or 4E5 on the nameplate in the engine compartment (next to the VIN).

πŸ”Ή BMW/Mini: 3-4 digit code (e.g. 300 or A58) is placed on a sign in the spare wheel well or on the door sill.

πŸ”Ή Mercedes-Benz: type designation 744U or 992U can be found on the front door pillar or under the driver's seat.

Important: on some models (especially the premium segment), the paint code can be encrypted in the VIN number. For example, at Porsche color is encoded in 3-5 characters of the VIN, and Jaguar Land Rover - in a separate electronic documentation file.

Where else can I find a paint code?

On some vehicles (for example, Ford or Chevrolet) the code is duplicated on the inside of the glove compartment or gas tank cap. You can also find it out from an official dealer using the VIN number - but they may charge a fee for this service (from 500 to 2000 rubles depending on the brand).

If the nameplate is worn out or missing, this will help VIN decoder. Free services like VinDecoderz or AutoDNA will show the base color, but will not take into account individual shades (for example, for Audi Exclusive or BMW Individual). For accurate results, it is better to use paid databases, such as Mitchell 1 or Identifix, where data on paint batches is stored.

2. Selection methods without factory code

What to do if the code is lost or the car has already been repainted? This is where alternative methods come to the rescue:

πŸ”§ Visual selection from the catalog - the most budgetary, but also the most unreliable method. The master compares the shade with physical samples (chips) from the catalog RAL, PPG or DuPont. Problem: Even in daylight, the eye can be off by 10-15% due to the effect of metamerism (when color looks different under different light sources).

πŸ“Š Spectrophotometer - a device that analyzes reflected light and determines the paint formula with an accuracy of 98%. Cost of service: from 1500 β‚½ in services. Popular instrument models:

  • πŸ”¬ X-Rite MA98 β€” used in 70% of premium car services;
  • πŸ”¬ Datacolor Spectro - more precisely for pearlescent and chameleon shades;
  • πŸ”¬ BYK-Gardner spectro2guide - a budget option for small workshops.

How does a spectrophotometer work? The device β€œshoots” a beam at 3–5 points of the body (for example, the hood, fender, door), then the program compares the data with a database of 100+ thousand shades and issues a recipe for tinting. Important: before measuring, the surface must be clean and matte (no wax or polish).

⚠️

Attention: If the car has already been repainted, the spectrophotometer may not show the original color, but the one that was previously applied. In this case, you will have to remove the paint layer down to the primer and analyze the factory coating.

3. Tinting: how to get the desired shade from a base color

Even knowing the paint code, the master has to tinting - the process of mixing base pigments to obtain an exact shade. Three factors are important here:

1️⃣ Recipe Database. Professional systems (eg PPG Nexa Autocolor or Sikkens Autowave) contain recipes for 95% of automotive paints. But for rare shades (for example, Lamborghini Arancio Xanto or Ferrari Rosso Mugello) may require manual adjustment.

2️⃣ Pigment quality. Cheap analogues (for example, Chinese bases) can give an unstable result: the shade β€œfloats” when drying or changes over time. Professionals use pigments from BASF, Axalta or Sherwin-Williams.

3️⃣ Mixing Conditions. Room temperature, humidity, and even the material of the mixing container affect the final color. Optimal parameters:

  • 🌑️ Temperature: 20–22Β°C;
  • πŸ’§ Humidity: no higher than 60%;
  • ⏳ Mixing time: at least 5 minutes at high mixer speed.

Critical mistake: using paint from different batches of the same manufacturer for tinting. Even PPG or Spies Hecker Shade may vary by 3-5% due to pigment production.

4. Types of automotive paints: what influences the selection

Not all paints are the same. Not only the appearance, but also the selection method depends on the type of enamel:

Paint type Features of selection Examples of shades Matching difficulty (1–5)
Acrylic (solid) Single layer, no metallic. The easiest way is to select it visually. Ford Race Red, VW Pure White 2
Metallic Contains aluminum powder. Requires analysis of particle size and shape. BMW Mineral White, Toyota Super Silver 4
Mother of pearl Changes hue depending on viewing angle. You need 2-3 measurements with a spectrophotometer. Audi Nardo Grey, Lexus Sonic Titanium 5
Chameleon (color-shift) Contains several layers of pigments. Selection only in the laboratory. Mazda Soul Red Crystal, Nissan Midnight Purple 5
Matte Requires precise selection of not only color, but also the degree of matte (measured with a gloss meter). Tesla Multi-Coat Red, Mercedes Designo Magno 4

πŸ”Ή The most difficult case β€” paints with a β€œchameleon” effect (for example, Mazda Machine Grey or Ford Liquid Blue). They consist of 3–5 layers with different pigments, and they can only be selected in specialized laboratories (cost from 5000 β‚½).

πŸ”Ή The simplest - acrylic paints without effects. For example, VW Tornado Red or Renault Bleu de France> can be selected visually with 90% accuracy.

5. Where to order paint selection: service vs laboratory

The choice of location depends on the budget and quality requirements:

πŸ”§ Car service (average bill: 2000–4000 β‚½)

  • βœ… Fast (1-2 hours);
  • βœ… You can immediately paint the part;
  • ❌ Risk of error up to 15% (if there is no spectrophotometer).

πŸ§ͺ Specialized laboratory (average bill: 5,000–10,000 β‚½)

  • βœ… 99% accuracy even for rare shades;
  • βœ… Selection warranty (usually 1 year);
  • ❌ Longer (2-3 days) and more expensive.

🏠 Independent selection (budget: from 500 β‚½)

  • βœ… Cheap (chip catalog RAL costs ~1000 β‚½);
  • ❌ Risk of error up to 30%;
  • ❌ No guarantee.
πŸ’‘

If you only need to paint a small part (like a mirror or bumper), try a mobile colorist service. The specialist arrives with a portable spectrophotometer and makes a selection on the spot. Cost: from 2500 β‚½, but saves time on a trip to the service center.

⚠️

Attention: Some services offer a β€œfree paint selection” when ordering painting. Often this is a marketing ploy: the master simply takes the closest shade from the catalog without checking it with a spectrophotometer. Always check what equipment is being used!

6. Common mistakes and how to avoid them

Mistake #1: Ignore year of manufacture. For example, Honda NH-731M (metallic gray) for models before 2015 is 12% lighter than for cars after 2018. Always check the code against the database for a specific year!

Mistake #2: Select color from photo. Even a professional camera distorts shades. For example, BMW Estoril Blue In photos it often looks purple, although in reality it is a deep blue.

Mistake #3: Save on test application. Before painting completely, always apply paint to a test plate and compare in daylight. Cost of the test: 300–500 β‚½, but it will save you from repainting the entire part.

Mistake #4: Ignore the type of varnish. Glossy varnish enhances color saturation by 5–7%, while matte varnish mutes it. If the original car is covered ceramic clear coat (like Tesla), and you use standard acrylic varnish, the shade will be different.

πŸ’‘

The most common cause of color discrepancy is improper surface preparation before measurement. Even a thin layer of polish or wax distorts the spectrophotometer readings by 8–12%!

7. How much does it cost to select paint in 2026?

Prices depend on the method, region and type of paint:

Service Cost (β‚½) Time Accuracy
Selection by code (without tinting) 500–1500 10–30 min 90–95%
Spectrophotometer in service 1500–3000 1–2 hours 95–98%
Laboratory selection (for chameleons/mother of pearls) 5000–12 000 2–3 days 99%
Tinting + test application 2000–4000 3–5 hours 97–99%
Selection by eye in a garage service 0–1000 30–60 min 70–85%

πŸ’° How to save money?

  • πŸ“Œ Order selection and painting in one place (up to 20% discount);
  • πŸ“Œ If you need to paint several parts, ask for group coloring (15-30% cheaper);
  • πŸ“Œ For budget cars (for example, Lada or Datsun) a visual selection from the catalog is sufficient RAL.

FAQ: Answers to frequently asked questions

Is it possible to choose paint from a photo?

Technically yes, but the accuracy will not be higher than 60%. Even professional programs like Adobe Color or Paint.NET do not take into account:

  • πŸ”Ή Lighting when shooting;
  • πŸ”Ή Camera white balance settings;
  • πŸ”Ή Metallic/pearl effects.

For an approximate result, you can use the service ColorSnap Match from Sherwin-Williams, but this is not suitable for painting.

What to do if the paint code is erased?

Options:

  1. Contact an official dealer with a VIN number (cost: 1000–3000 β‚½).
  2. Use a spectrophotometer to analyze the original paint (if there are unpainted areas, for example, under the hood).
  3. Find a similar car of the same year and market (for example, through clubs of brand owners).

⚠️ Do not trust data from public databases like PaintRef.com> - They often lack updates for the last 2-3 years.

Why does the color differ after painting in the sun and in the shade?

It's called metamerism - the property of paint to change shade under different lighting conditions. Reasons:

  • πŸ”Ή The size of metallic particles is incorrectly selected;
  • πŸ”Ή Pigments from different manufacturers were used;
  • πŸ”Ή Mismatch of varnish type (for example, acrylic instead of urethane).

Solution: repaint the part using original materials or order laboratory analysis.

Is it possible to tint the paint yourself?

Technically yes, but this will require:

  • πŸ”Ή Professional mixer (from 20,000 β‚½);
  • πŸ”Ή Pigment base (set from PPG costs ~15,000 β‚½);
  • πŸ”Ή Scales accurate to 0.1 grams;
  • πŸ”Ή Recipe catalog (for example, MixIt or ColorNet).

This is not practical for one-time use. It is better to order tinting from a service center or buy ready-made paint according to the code.

How to check the quality of the selection before painting?

Algorithm:

  1. Apply paint to a test plate (metal or plastic similar to the part).
  2. Wait for it to dry completely (24 hours for acrylic, 48 for mother-of-pearl).
  3. Compare with three types of lighting: daylight, fluorescent lamp, LED.
  4. Check the color at 45Β° and 90Β° angles (especially for metallics).

If the shade matches in 90% of cases, you can paint it. If not, ask for the recipe to be adjusted.
