H, C, L and number of colors inputs too permissive

[ZorGleH]

H, C, L and number of colors in the palette inputs could be constrained to allowed values. When you enter values with keyboard, you can enter values outside the range.

Something to consider, thanks.

I think it might be more intuitive to have the input value changed to the closest possible value in that particular range.

This seems to be the right feature to implement!
