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.
