A Word About RED

Since the colour-wheel for Hue (H) is circular, what we commonly call "red" straddles quite naturally the zone from ...358, 359, 0, 1, 2 ... etc. However, the range sliders used on the dropper-tool panel are linear, which means that "...358, 359" needs to be treated as one zone, and "0, 1, 2..." needs to be treated as another, i.e. as though they were two different colours. This is, frankly, a small limitation. It is possible that later editions of RD-D will address this issue.
