PMS Cool Gray 3 C is a Pantone Matching System color recognized for its use in branding and identity applications that require a reserved, neutral visual effect. With a low chroma, a slightly cool undertone, and a relatively high light reflectance value (LRV 58.47), it delivers a clean, understated, and professional appearance. The overall vibe of this color is subtle, technical, muted, restrained, and contemporary.
PMS Cool Gray 3 C appears light in value, with a light reflectance value of 58.47. The color displays a cool undertone, due to its placement near the yellow-blue axis (hue angle ~89°). PMS Cool Gray 3 C has low saturation and reads as a subdued, nearly achromatic gray. This color tends to maintain its neutral appearance in most finishes, but can take on a slightly bluer cast in gloss and under cool lighting.
PMS Cool Gray 3 C is frequently specified for brand systems requiring a consistent, unobtrusive gray for backgrounds, text, or secondary graphic elements. This color is often seen in corporate stationery, signage, displays, and trade show environments where a balanced, professional look is preferred over bold or saturated colors.
PMS Cool Gray 3 C is effective when a space or object needs to maintain neutrality without appearing warm or stark. It performs best under neutral to cool lighting conditions; under warm or incandescent light, it may appear slightly more muted or taupe. Users should be aware of the potential for finish sheen to affect coolness and visibility of the undertone, especially in high-gloss applications. Compared to other cool grays in the PMS system, PMS Cool Gray 3 C is lighter and less saturated, causing adjacent colors—especially warm tones—to appear more distinct.
This Pantone PMS color is defined by the Pantone Matching System standard. Evaluate the color using a physical Pantone reference and a real paint sample in the intended lighting and finish. Paint appearance varies by finish and lighting.

If you are using PMS Cool Gray 3 C for prototypes or concept models, select a paint format and sheen that matches your production intent, such as spray paint for most display-size elements. Evaluate PMS Cool Gray 3 C alongside an official Pantone reference to verify color alignment under your actual lighting and finish. Testing the paint on a material that matches your final product is the best way to confirm visual accuracy before full production.
PMS Cool Gray 3 C paint is custom made for each order, so it is important to select the correct sheen and product type before purchasing. Custom-mixed Pantone paint is typically not returnable. Always verify color needs and, if possible, test a sample in your intended environment before committing to larger quantities.
PMS Cool Gray 3 C can appear differently depending on the substrate and finish due to differences in absorption, surface texture, and reflectivity. These factors can influence how light interacts with the paint, making the color look cooler, warmer, or more muted. For critical projects, evaluate PMS Cool Gray 3 C on the same material and under the same lighting as the final use environment to ensure brand alignment.
PMS Cool Gray 3 C is defined as a brand color and is intended for new applications where visual alignment with a Pantone standard is the goal. It is not formulated for touching up existing finishes, as color and sheen can vary by substrate and prior coatings. For spot work or surface repair, sending a physical part for custom matching is recommended instead of relying on the Pantone PMS formula.
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 Cool Gray 3 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 Cool Gray 3 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.
