It's basically a question of convention whether it should be Cold/Warm or Warm/Cold.

But your're right, code and comments are inconsistent.

I tested agains 6.5.0.0 and I realized thet I completely inverted Cold/Warm compared to previous versions. Actually, it's not the comment that is wrong, it's the code.

I will submit a PR to get back to RGBCW (6.5.0.0) instead of RGBWC (6.5.0.9).

@s-hadinger from my offline position I thought so too. So yes pls adjust the code for legacy reasons.

PR #5766 submitted. It should supersede this PR.
