[Gimp-user] Gimp newbie trying to get a job done.


I have been burning brain cells on this for a while.  I do have one final question.  Like in the case where 
there was green in all sorts of places, how could I go and change all the green areas to any color that I 
want, in only a couple of clicks?

This is actually a much simpler graphic than what I would normally be 
using, but you get the idea. In as few clicks as possible, I just want 
the green areas, and want the rest of the graphics transparent.

The great thing about Gimp is there is always another way.

Have to confess, my first thoughts were with the G'mic plugin but maybe a better way for your specific case 

Convert the image to indexed with a small number of colours
Edit the colour map so anything non green is (say) white
Back to RGB mode and colour-to-alpha to remove the white.
