Thanks a lot Alberto.
With “the controls let you pick any hue …” do you mean the conbination selected with controls is the resulting color or it is the color that will be blended with original one?
I understand than the tool is not intended to change one color to another specific color because it is not possible to select lightness/brightness (one question arise because I can control lightness/brigbtness with the slope/gain/… in the same tool so with more effort can be make result near desired).
So I understand tool is better to use to make slight modifications as some kind of “white balance” as you explain.
I understan also there is no way (exept trial and error) to know what will be the final result, isn’t it?
I will try picker in the way you comment. I need some experiment.
Thanks a lot.
