As painter we use not always all colors, we choose some, for practical and aestehic reasons.
Finally we try to find an nice color association between… Colors and tones.
I think a dynamic palette would be great addition for us all, like this:
A) Pick a foreground color with the eyedropper
B) Get the corresponding complementary, tertiary, tris, analogous colors (3 min, maybe better 5) derived from the tonal value and hue of the foreground color picked before
Of course this color harmony system works only efficiently if we are using the RYB color wheel, and not… the odd TV color system, rgb.
