Gimp: change one colour to another?
I have a JPG image that is made up of different shades of blue and pink. I would like to change all the pink in the image to the equivalent shade of green.
I know about GIMP's "Select by Color" tool, but my problem is that there isn't just one shade of pink in the image, there are about 10, from dark pink to very light.
So I can manually select all the dark pink and change it to dark green, the slightly lighter pink and change it to slightly lighter green, etc.
But this is laborious and doesn't give a very good result.
Is there any way that I can map all the shades of pink to an equivalent shade of green?
