let us assume for a moment that I am a total fool that can barely operate an image manipulation tool
let us further postulate that I have been attempting to recolor a texture by converting parts of it to monochrome (bits that are effectively a solid color with shading) and adding additional flat color layers set to multiply mode
this actually worked out very well
however
I would like to blend the edges of some color regions together via some operation that leaves my color regions intact and easily color changed later
is this possible [spoiler]using the GIMP[/spoiler]?
