What Are CSS Named Colors?
CSS defines 148 color keywords that can be used anywhere a color value is accepted in stylesheets. Names range from common ones like red, blue, and white to more specific choices like cornflowerblue, darkolivegreen, and rebeccapurple.
Named colors are convenient for prototyping, debugging, or whenever you want readable color values in your code. This tool helps you find the named color closest to any arbitrary color.
How Matching Works
Distance is calculated as Euclidean distance in RGB space: the square root of the sum of squared differences for each channel. An exact match (distance 0) means the color is identical to a named color. Larger distances mean the match is approximate.
