Re: behaviour of colour wheels

The colorweel lets you select a color, the question is how that color is
applied to the image, ie. is it an add, mult or gamma?

An add or mult will affect you white points, 1, gamma will not. Looking at
Photoshop's Color Balance, it looks more like it's close to a gamma correction.
Even if you select highlights in the CB dialog, the whites says white.

Hope this helps.
