Well... you shoulda sent a patch for that if you wanted to reserve it.
As far as I can tell, there's currently no support for anything
color/label-related in evolve. But maybe you're talking about hgview.

The most common forms of color vision deficiency (8% of men) are about
weakness or absence of red receptors. Baseline human brightness
sensitivity works something like this (with gamma factored in):
brightness = red * .1 + blue * .2 + green *.7
In my case, it's more like red * .03: I can see it, it just is not
nearly as intense as other colors. So I can't easily distinguish any
3-bit color pair that is different just in the red bit... except
black/red. So that means in the basic 8-color palette:
x00 red/black <- ok relative contrast
x01 blue/magenta <- bad
x10 green/yellow <- worse
x11 cyan/white <- worst
Given yellow is already chosen and white and black are terminal default
fg/bg colors, that basically leaves me with red and blue/magenta if I
want to use colors (as opposed to attributes) for phases. So I'd accept
one of the following choices:
As for changeset obsolescence states, there's a pretty good argument to
make that they should be orthogonal to colors (ie attributes),
especially as you can have obsolete secrets and troubled drafts. Dim for
obsolete and underline for troubled seem good. I'm currently using
inverse for checked out.
Mathematics is the supreme nostalgia of our time.
