I think that the kind of sunsets I want to draw aren't as blue as I think they are, and I need to come at them with very different colors (more beiges than blues)... but I made one with exagerrated blues, and it was educational. It's hard to get orange reflections to sit on top of the blues - they blend into other colors.
Also shown here: the set as I use them; studies in artificial cereal colors, blues, and greens.
I think I need a lot more days off to get the hang of these... But it is delightful to LEARN by trying.
