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.
