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.
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".
If all you want is 'middle' and that doesn't need to be well defined,
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.
Mute/off, if required, would be the same as the lowest setting.
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...
Have fun,
Arnold
To what kind of user chosen color scheme do you refer to?
