I don't like this every-app-chooses-its-own-colors at all. Though I do
understand that sometimes you need more colors, but that still is different
from "I define my apps colors on my own because I think that is cool". The
later results in apps with black text on dark-gray background in an otherwise
very light desktop-environment => bad. Or in apps with white window background
while the rest of the desktop is optimized for on-stage-in-the-dark with black
background and red foreground => bad. Or it results with using two collors to
"distinguish" which half visually impaired people can't discriminate =>
bad.
Thats why I really advocate using the systems color-scheme as much as possible
(and a bit more) every time the discussion regarding colors comes up.
Have fun,
Arnold

I don't want 'a' middle, I want a special middle. Like 0dB between -48dB and
+12dB (the middle doesn't have to be in the geometrical middle). And I want to
know when that special middle value is reached by looking at the color.

If all you want is 'middle' and that

then two colors will do. I suggested blue because of the ugly brown you
get between green and red. With blue the middle will likely be some kind
of purple, which may or may not be optimal. Maybe black to red would be
nicer, it just gives you an increasingly bright red. Previously:
Two colors simply isn't enough. You need a color for low, a color for
middle and a value for high. And then you haven't even looked at a
fourth color for mute/off.
And fading from green directly/linear to red gives an ugly brown in the
middle. It looks much nicer to go across yellow. And then you can really
use that third color to stand for a special step, not just "in the
middle of the slider". That's actually a neat idea, color for
immediate visual feedback. I
imagine the problem is the colors. What would be sane? I guess three
basic colors and interpolate between them?
low = blue
middle = yellow
high = top
It needs to be rather intuitive. I guess the more colors the less
intuitive it will become. Maybe two are enough.
I wonder which color would best represent 'low' or 'bottom'.
Blue, black?
I suggest you keep it simple, i.e. only two colours if possible, but
make them configurable for the benefit of those with visual
disabilities. Mute/off, if required, would be the same as the lowest
setting.
There is a difference between mute/off and the lowest setting. At least there
can be.
Software-mixers might not make that discrete step between off and almost
silent. But some hardware mixers in devices do make that difference. And there
it will make a difference to your ear whether the signal is attenuated by 36dB
or muted.
If these
colors are taken from the color-scheme the user has chosen, I
feel confident, that these are suitable for all kinds of color-blindness
(otherwise the color-scheme is chosen wrongly). But I don't know (yet)
which color roles to use from the color-schemes...
To what kind of user chosen
color scheme do you refer to?
