Selective Color replacement tool

[GoogleCodeExporter]

Hi guys,

It would be useful for me to have a tool where I can replace one index with 
another on a part of my canvas. 
Example: 
I have a drawing with some red, some blue and some green. 
I want part of the red to become yellow, but also a part should be the same so 
changing the color value for the red index is not an option.
The color replacement tool would not work either, and filling every part of my 
image that is red with the floodfill would cost a lot of time if the parts are 
not all connected, for example on 1px linework.

Now I would really like a big brush that I can move over the parts of the image 
where I want the color replaced! Color to be replaced would be background 
color, new color would be foreground color, and by clicking with my brush all 
the red pixels under the brush should turn yellow.

Even MSpaint has this useful function, would it be possible to get this in 
grafx2 too?

Daniel

Go to effects-menu and select "Stencil"
Click your background-color (color to be replaced)
Invert the selection
Now you can only draw on the background-color...

Note that when the stencil window is open, if you click outside the window on 
your image, it tags/untags the colors that you touch.

Can also be done with shades insaturating mode - very useful if you have 
multiple colors to replace at once.
