Hey guys! I've been cracking away at a map now for a few days and I've made quite a few beginner's mistakes, but there's one issue I've not yet been able to resolve. Because my conversion over to BMP was not overly successful (I had a lot of unknown colours) I have been left with no blends between different grass colours, and I'm having to input them all in by hand. Now, I'm happy to take the time to perfect something, but damn, this will take a long time. Does anyone have any idea how to do this on a large scale quite quickly? Many thanks in advance! Here's a little screen of progress so far:
