CSS named colours
The 141 colour keywords every browser recognises, each with the figure a colour picker leaves out: how much contrast it has, and therefore whether anything can be read on it.
The list is frozen. It was settled in CSS 2.1 and the CSS Color specification has added no keywords since, which is why rebeccapurple — added in 2014 in memory of Rebecca Meyer — is the last one anybody remembers being new.
