--- Comment #1 from Ivan Batalin <morganh...@ya.ru> ---
The most easy and powerfull feature will be to invert color to alpha action -
to generate inverted mask (alpha of all colors, but selected). Must be an a
filter option to do this.
In this case we can add, for example two filters^ HSL and Color2Alpha, and have
full control above colors. Very usefull for Photography retouching and Color
correction.
At now, to do this action you need to do the next actions:
1. Create Copy layer of source image (paint layer, or layer group)
2. Add a filter layer with Color2Alpha filter
3. Merge both of them into a group
4. Add filter mask to filter Layer with ColorAdjustment effect to invert alpha
channel
5. Add filter mask to filter layer with HSL/HSV effect to change color
Must be (simple and fast):
1. Add Color2Alpha filter mask to Paint layer or Layer group with inverted
option
2. Add HSL/HSV filter mask to Paint layer or Layer group to change color
