Date: Mon, 30 Jan 2023 21:48:20 +0000

[Message part 1 (text/plain, inline)]

Look at the results of

(require 'color)
(message "reduce by 100 = %s" (color-lighten-name "Black" 100))
(message "reduce by 0 = %s" (color-lighten-name "Black" 0))

In emacs 28.2 they give "#ffffffffffff" and 0 as expected.
In emacs 30.0.50 they give 0 and 0
