Cool violet is purple with the light held back and the blue kept ahead of the red. It is the True Winter purple, darker than Bright Winter's violet and cooler than any Summer plum. It is the palette's answer for anyone who wants a dark that is not black or navy and a color that is not blue.
Where it sits
Cool violet is an anchor color in True Winter. Nothing on the same side of the warm–cool line comes within twenty points of it; the nearest is Bright violet #6A2FB5 in Bright Winter at 24. That makes it a clean test. If it suits you, you are in this palette.
At RGB 91, 42, 131 the blue runs at three times the red and the green is low. That makes it a blue-violet, and the low light makes it a dark one. Add red and it slides toward Deep Winter's royal purple. Add light and it becomes Bright Winter's violet. Take the saturation out and it is a Summer plum. Cool violet sits in the middle of all three.
A True Winter wears it as a strong dark. A coat, a knit, a dress worn alone with black shoes. It pairs with black, true white, charcoal, and icy blue, and it does something good with emerald that few purples manage. It can carry an outfit as the only color in it, and it tends to prefer that.
Retailers call it violet, purple, royal purple, grape, amethyst, or plum, and most of what sells under those names is either redder, which is Deep Winter, or greyer, which is Summer. Hold the garment against a cool pink. Cool violet looks blue by comparison. A royal purple looks like a darker version of the pink.
Easily confused with
There is no close neighbor. True Winter's own sapphire is twenty-one points off and bluer. Bright Winter's bright violet is twenty-four points off and lighter. Deep Winter's royal purple is twenty-nine points off and redder. On a Bright Winter, cool violet looks a little heavy. On a Deep Winter, it looks a little blue. On a True Winter it sits where it should.
