From my understanding, when I use Color -> Hue-Chroma or Hue-Saturation, and slide Hue value, it adds this value to the hue of every pixel in the selection.
What I want is to just "colorize" the picture by setting every pixel's hue to the same value, like adjusting absolute value, not relative.
It would also be wonderful if there would be a way to do the same for saturation and lightness.
How could I do that?
