did you know this is inherited from x11? blame them for copying the bad colors from there https://developer.mozilla.org/en-US/docs/Web/CSS/named-color
Initially, in CSS Level 1, only 16 basic colors were defined, with orange added in CSS Level 2. Web designers found this list too short, and browser vendors added numerous names for colors based on the X11 color names. In SVG 1.0, then in CSS Colors Level 3, these names got standardized, formally defined, and made uniform (some had different spellings that are now aliases). They are called extended color keywords, X11 colors, or SVG colors.
In CSS Colors Level 4, an additional color, rebeccapurple was added to honor web pioneer Eric Meyer.
