Subject: bug#74055: 31.0.50; color-lighten-name not lightening black
Date: Mon, 28 Oct 2024 09:27:29 +0100	[thread overview]
Message-ID: <m2wmhsk4y6.fsf@gmail.com> (raw)

The function color-lighten-name doesn't work as I would expect for
black:

  (color-lighten-name "#000000" 50)
  => "#000000000000"

I think there is even a test that checks that, in color-tests.el:

(ert-deftest color-tests-lighten-name ()
  (should (equal (color-lighten-name "black" 100) "#000000000000"))

I don't understand this, and it is different from what I'd expect, and
tools for the web return, for example
