Pantone® PMS 421 C. Paint And Spray Paint. MyPerfectColor is the official licensee of Pantone and authorized to reproduce the Pantone Matching System colors in spray paint and other paints.
PMS 421 C, from the Pantone PMS collection, presents as a muted, light-to-mid gray with a neutral to slightly cool orientation. The color’s vibe can be described as understated, professional, balanced, technical, and unobtrusive. It occupies a midpoint in light reflectance, supporting applications where visual neutrality and low distraction are required in branding and specification environments.
- PMS 421 C exhibits a moderate lightness, with its LRV of 49.89 placing it near the center between deep and pale grays. - The color reads as a cool, neutral gray, displaying no strong undertone of warmth. - PMS 421 C has low chroma, resulting in a desaturated, functional appearance. - The undertone is predominantly a clean, subtle blue-gray, especially visible under cool white lighting. - This color shows some sensitivity to finish, appearing marginally lighter and cleaner in higher sheens, and more subdued or powdery in matte or eggshell finishes.
This gray works well as a background or supporting color in branded environments, marketing displays, or prototyping applications where a sense of technical competence or quiet professionalism is needed. It maintains visual clarity without drawing attention away from branding elements or primary colors. When using PMS 421 C, consider that changing lighting temperature and finish can accentuate its coolness or add visual softness. Compared to similar neutrals, PMS 421 C retains a steadier neutrality without evident beige or strong blue shifts.

Pantone books provide a visual reference standard for PMS 421 C under specific printing and lighting conditions. Actual paint made in PMS 421 C may look different, especially when applied to various substrates or using different sheens, such as matte or gloss. For brand and display applications, always sample PMS 421 C paint on your actual material and in your intended lighting before making final decisions. This helps confirm you are achieving the intended brand look.
The SDS for paint made in Pantone PMS 421 C is determined by the type of paint or coating you select, such as spray paint or urethane, not by the color code itself. You can find the appropriate SDS in the SDS library on the website by selecting the specific product type you intend to use. If you need help identifying the correct SDS for your PMS 421 C paint, contact customer support with details of the product format you have chosen.
Pantone PMS 421 C is specified to create consistent, recognizable visual experiences across brand environments, displays, and signage. Using a standardized Pantone code like PMS 421 C allows teams and vendors to communicate clear color expectations, helping to maintain brand consistency across different materials and production runs. For best results, confirm the color on physical samples and ensure your application matches the intended appearance under project lighting.
To maintain a uniform appearance when using PMS 421 C on large surfaces, use consistent application techniques and plan your work area to allow even coverage. Apply each coat completely before moving to the next. Use the same batch and product type throughout the project to avoid subtle color or sheen differences. Be aware that changes in finish or lighting can impact how the gray is perceived. Testing PMS 421 C on your specific material and spacing overlapping passes can help prevent patchiness.
Unfortunately, no.
Some manufacturers specify Pantone colors as touch up for their products, but Pantone does not work well as a proxy for a touch-up solution (for a litany of reasons such as it doesn't include sheen and Pantone color tolerances are not tight enough for touch up). When we match Pantone colors we are matching to a swatch in a Pantone book - not to your product.
The only way we can provide a touch-up solution for your product is for you send us a part. We would use the part to create a touch-up grade match. Unfortunately, there isn't an effective way to 'spec' the color well enough to produce a touch up without the part.

To make spray paint matched to Pantone PMS 421 C. MyPerfectColor uses an acrylic enamel which is a fast-drying durable coating suitable for interior or exterior use. MyPerfectColor custom spray paint enables you to conveniently achieve a professional spray-smooth finish in any color in any sheen. It sticks well to most surfaces including metal, plastics, powder-coatings, cabinets and primed or previously painted wood.
The 11oz spray will cover about 20 square feet per coat. Keep in mind that it is difficult to gauge how much spray you'll need as it is highly dependent on how it is applied. It is better to have too much than run short.
While MyPerfectColor can provide PMS 421 C in paint, we don't provide any crossover information. We've found that every paint company offers its own unique selection of colors and rarely does a color have an exact equivalent in another company's color collection, especially for a color collection like Pantone which is designed for bright colors and inks.
