This page contains the Firefox desktop colors as defined in the tokens stylesheet as of 29th April 2025. Many of these colors are defined in the oklab color space.
The RGB and hex values are also included. These are approximations of the true color. We convert them to standard RGB and round and truncate the values to remain with the RGB 24-bit color space, which has a narrower gamut than the oklab color space.
For each color, we show the Firefox color on the left and the standard RGB approximation on the right. If these two colors look visually different, then either the approximation calculation has failed or you have a wide gamut display and standard RGB cannot represent the color.
