I'm trying to make a color spectrum that I will turn in to a gradient where the darkest colors are little bit lighter.
I think i've found the beginning of what i'm looking for by creating a gradient like this

then going to generic/mathmap/combine/convolve
then press enter and I get this

what do I do next to make the spectrum have total saturation (no gray mixed in) ?
I have changed the lightness and that seems to make it more colorful but I don't know exactly what to do to make it "even" any thoughts?
