@duerer I am not exactly sure how this is calculated but when you have RGB = (1, 0.5, 0.5) for instance the Value is of course 1.
When you then lower the Value to 0.735, the red, green and blue channels all get reduced to about half their values.
To be more exact: (0.5, 0.253716, 0.253716).
With RGB 0 (1, 0.8, 0.2) you get, if you reduce the Value to 0.735;
(0.5, 0.401725, 0.104275).
