There are many ways to do color interpolation. The quick way is to do it in the RGB colorspace. If You might try using the hilite color.vi located in the picture control palette. It takes a given color and returns the colors mixed with white and black. If you want a smooth ramp, it would be more efficient to determine the first color and last and you can linearly interpolate between the R, G, and B coordinates independently. Another way is to start at your color and linearly move to white by linearly interpolating the R, G, and B values independently. Then do the same towards black. If I'm misunderstanding your question, please post more details. Greg McKaskle
