I have a Colorbar (Row of colors) representing 1000s of color.
The colorbar has two sliders on the top of it. When I move the sliders, I should get the color represented by lower slider and upper slider. I cannot apply Interpolation to get these extremes. because R, G, B components
not moving in linear fashion. In first 1/3rd of colorbar R is increasing, B is decreasing, but G is constant.
next 1/4 th R is increasing, B is constant, G is decreasing and so on.
How can I create mathematical model,so that I can get a exact color values of chosen sliders.
Sorry for my poor English

Use either of the HSL or HSV color spaces, interpolate in that space, and then convert to RGB when needed.
