It would be nice to be able to select white in the colour wheel somehow. I’m thinking of using it for lights, I would like to be able to select a colour or a white, maybe some sort of pre-set set of whites, IE daylight or candle or brilliant etc.
By holding down the center of the color wheel, you can change between hue, saturation, and value mode; using a combination of those you can select white. You can try it here (just make sure you don’t click on the edge, or it doesn’t seem to work very well).
