K23 Nissan color: a complete guide to selection and restoration

Car owners who are faced with the need to select paint to repair a bumper or door often see the marking in the service book or on the nameplate K23. This code is a unique shade identifier that is used on the assembly line to paint body panels. Understanding what this acronym means is critical to getting your vehicle back to its original appearance without losing its factory aesthetics.

Color Nissan with index K23 belongs to the category of gray shades, but its exact interpretation may vary depending on the model year and region of delivery. Owners Almera, Qashqai or X-Trail You should know that the visual perception of gray color is highly dependent on lighting, which makes choosing paint on your own without professional equipment a risky endeavor.

Characteristics and name of shade K23

In the manufacturer's official palette code K23 most often corresponds to the shade “Silver Grey” or “Silver Grey”. This is a classic color that was highly popular between the mid-2000s and early 2010s. A special feature of this pigment is the presence of metal particles, which give the surface a characteristic shine and depth, hiding minor irregularities in the body.

However, it is important to understand that the color name may vary depending on the specific model. For example, on compact hatchbacks this shade may look a little cooler, while on large crossovers such as Patrol, it may feel warmer due to the larger body areas. Nissan often adjusts paint formulations for different generations, so even with the same K23 code, visually the shades may differ slightly.

When viewing the car in cloudy weather, the K23's color appears to be a muted gray, but in direct sunlight it reveals a full silver glow. It is this play of light that makes it one of the most practical options, since dust and minor scratches are less noticeable on it compared to black or white paintwork.

Technical nuances of selecting paint according to code

The process of selecting paint by code K23 requires accuracy, since computer selection does not always take into account the degree of fading of the old coating. If your car is more than five years old, the factory paint may have lost some of its pigment or oxidized, making the new coat too bright and contrasty. Specialists use spectrophotometers to analyze the current condition of the body in order to adjust the paint recipe.

It is important to consider that a paint code is not just a number, but a complex chemical composition. It includes base pigments, metal powder (for a metallic effect) and binders. An error in proportion of even 0.5% can lead to the fact that after drying the color will become noticeably darker or lighter than required.

For quality repairs, it is necessary to consider the type of varnish that is applied over the base. Factory varnish has a certain thickness and light refractive indices that need to be reproduced. If you are planning a DIY renovation, make sure you use a varnish that is compatible with the base. K23, otherwise dull spots may appear or the coating may peel off over time.

Attention: Do not attempt to mix K23 paint with leftover paint from other vehicles, even if they appear similar. Differences in formulations from different years of production can lead to irreversible delamination of the coating.

Where to find accurate color information

To be sure that you are looking for the exact shade that was installed at the factory, you need to find a plate with the VIN and paint code. In cars Nissan This label is usually located on the B-pillar on the driver's side or on the inside of the door. On it you will find a color code, which often consists of two letters and two numbers, for example, K23.

Sometimes the code can be encrypted differently, for example, as K23A or K23B, where the letter indicates a modification of the shade or type of paint material. In such cases, it is better to turn to the official spare parts catalogs, where the decoding will be given taking into account all the nuances. For models Teana and Murano The plate may be located under the hood, on the partition of the engine compartment.

If the plate is damaged or erased, you can use the “search by VIN” method. Specialized services or official dealers can provide complete information about the vehicle’s equipment, including the factory color. This is especially true if the car has been repainted previously and the current color on the body does not match the factory color.

In some cases, especially on older models like Primera or Sentra, the code can be indicated in the service book in the “Description of the vehicle” section. However, documentary information is not always relevant if the body has been repaired, so visual verification with the plate is mandatory.

Features of restoration of body elements

When repairing parts painted in color K23, it is necessary to follow the technology of applying layers. First the primer is applied, then the base, and only then the varnish. Skipping any step or not allowing the drying time between coats may result in defects. For metallic gray shades, even application of the base is critical to avoid streaking.

If you are doing the repairs yourself, use a spray gun with an adjustable spray gun. For color K23, the optimal pressure is about 2-2.5 bar, and the distance from the nozzle to the surface is 15-20 cm. Too close a distance will lead to drips, and too far will result in a dry spray that will not have the desired shine.

Pay special attention to surface preparation. The old varnish must be thoroughly sanded so that the new paint has good adhesion. Use P600-P800 grit abrasives to matt the surface. Remember to use anti-silicone before applying paint to remove dust and grease.

⚠️ Attention: When working with metallic paints, be sure to use a respirator with filters class FFP2 or higher. Microparticles of aluminum and other metals are dangerous to the lungs if inhaled for a long time.

After the base has dried, varnish is applied. To achieve a “deep mirror” effect, two-component varnishes with the addition of a hardener are often used. Mix the components strictly in the proportions specified by the manufacturer and use only clean containers. Leftover K23 paint can be stored in tightly closed containers in a cool place, but no more than a year.

Nissan grayscale comparison chart

To avoid confusion with similar colors, below is a table comparing K23 to other common gray shades in Nissan's palette. This will help you more accurately determine which code is required for your repair.

Color code	Shade name	Years of manufacture (approx.)	Features
K23	Silver Grey	2005-2015	Classic silver gray with medium shine
K24	Dark Grey Metallic	2008-2018	Darker, graphite shade
QAB	Gun Metallic	2010-present	Deep dark gray with a bluish tint
K22	Light Silver	2000-2010	Light, almost white silver color
K23A	Silver Grey (New)	2012-2018	Updated formula with increased mother-of-pearl content

As can be seen from the table, even small changes in the code can indicate a significant difference in the composition of the paint. For example, option K23A may contain additional pigments to make it more fade resistant, but may be visually different from the original K23.

What is the difference between K23 and K23A?

The difference lies in the composition of the binders and the size of the metal particles. Version A has been developed to improve adhesion on new types of soils and improve UV resistance. Visually they are almost identical, but when mixed they can give a “stain” effect due to the different structure of the metallic luster.

Tips for caring for K23 body colors

Metallic gray, despite its practicality, requires regular maintenance to maintain color saturation. It is recommended to wash the car every 10-14 days, especially in winter, when the roads are sprinkled with reagents. Chemicals can attack the varnish, causing the color to fade K23.

It is advisable to polish the body once every six months. This will not only restore shine, but also create a protective layer that will repel dirt and moisture. Use soft polishes without abrasive particles to avoid damaging the varnish layer. For cars Leaf and Ariya with their smooth surfaces this is especially important.

Avoid using hard bristle brushes when washing. They leave micro-scratches that accumulate over time and turn a smooth surface into an “orange peel” appearance. It is best to use a microfiber mitt or a touchless washer.

Attention: Do not wash your car in direct sunlight. Rapid drying of water leaves limescale marks that are difficult to remove and can damage the varnish if you try to wipe them off with a dry cloth.

Common repair mistakes and how to avoid them

One of the most common mistakes is ignoring the surface preparation stage. Many car owners believe that it is enough to simply sand the scratch and paint it over. However, without thorough degreasing and priming, the new paint will quickly peel off, especially in areas of temperature changes.

Another mistake is using inappropriate solvents. For metal-filled paints such as K23, specific thinners are required that ensure the correct drying time. Thinner that is too fast will result in dry spraying; thinner that is too slow will result in drips.

Often, owners try to mix K23 paint with paint from another vehicle, hoping to save money. This is a serious mistake, since even visually similar colors can have different chemical bases. The result will be incompatibility of layers and the need to repaint the entire part.

Do not forget about the need to “transition” (stretch) the color during local repairs. If you paint only one door, the paint on it may not match the adjacent panels due to fading of the old coating. In such cases, it is necessary to smoothly shade the new paint onto adjacent parts.

⚠️ Attention: If you see that the old paint on the body is very faded and has become dull, do not try to simply paint it with a new layer. First you need to restore the color with a base coat to the level of fading, and only then apply a new varnish.

FAQ: Frequently asked questions about K23 color

How to accurately determine the paint code if the plate is erased?

The most reliable way is to contact an authorized dealer with the vehicle's VIN code. They may ask for factory specifications. You can also order the service of a colorist at a good car service center, who will select the paint using spectral analysis for your car.

Is the color of K23 the same on different Nissan models?

Visually, the color may look the same, but the chemical composition may vary depending on the year and model. It is recommended to always use paint designed for a specific model or at least the same year of manufacture.

Can K23 paint be mixed with other shades of grey?

It is strictly not recommended to mix K23 with other codes, even those that are similar in shade (for example, K22 or K24). This will result in incompatible layers and a visual defect. Use only the original K23 base and correct the shade only with special pigments under the supervision of a colorist.

How much paint does it take to touch up one part?

For local touch-up of scratches, 10-20 ml is usually enough. To paint an entire part (for example, a door or wing), you will need about 150-200 ml of base and 300-400 ml of varnish, depending on the size of the part and the number of layers.

How long does K23 paint take to dry?

Drying time depends on temperature and humidity. At a temperature of +20°C, the base layer dries for 15-20 minutes before applying the varnish. The varnish dries until completely cured in about 24 hours. When using infrared drying, the time can be reduced to 1-2 hours.
