Tweak tool color modes are one directional

[Vladimir Savic]

It's impossible to change "direction" of H, S, L, O operations so those can decrease, instead of only increasing chosen color property. In other modes of this tool one is able to, by holding Shift key, turn deformations in opposite direction (i.e. grow/shrink).

It just depends on which color you apply, i.e. the color of the tool. For example, take a middle-saturation green object, enable H channel only. Now pick black color and Color Paint: saturation of the green will decrease. Now pick bright red and paint: green will grow in saturation. Same applies to the other channels.

hah... true. :(

It's just that I was using tweak tool for hours and then tried to "color-correct" objects. Holding shift wasn't that bad idea. Admit it . :)

Isn't it easier to hold one button, then to lose color you're working with. This especially applies to saturation and lightness of a color. It's quite easy, I guess, to transfer those two color properties to their opposites (250 <-> 5 for example). Maybe even hue could give interesting results, much like already existing randomize color, but not quite.

ok, i just added it - painting with Shift inverts the color you're painting (white to black, blue to yellow, etc.)

Thanks a lot. :)

You made my job a lot easier.

You've deserved a small present... Enjoy the work almost fully done by tweak tool....

Nice! Maybe you could submit a screenshot with this artwork for our gallery?

Of course.

But first there is a problem with color operations. It doesn't work correctly.

Draw red (255,0,0) rectangle and turn on "hue" only. Pick blue and brush over that object. It will change color of rectangle to blue, but holding shift will desaturate object, not paint it in yellow. Try to reproduce.
