This CL further improves the algorithm of color selection to:
 1) Disallow colors with very low saturation (currently the first line
    in the color picker).
 2) Prefer colors with lightness similar to the lightness of the current
    profile (this disallows the very dark colors for the very light
    colors and vice versa).
