CSS named colors explained

CSS defines 148 named colors — from aliceblue to yellowgreen — that browsers recognize by name. They span X11 colors (from the 1980s X Window System) plus additions in CSS3 like rebeccapurple(added in 2014 in memory of Eric Meyer's daughter). This tool finds the nearest CSS named color to any hex or RGB value using Euclidean distance in RGB space.
