Rock, huh? Thankyou for the advice -- I don't know why I thought of the tiles as separate things and totally forgot about color recycling!

working on a different, 8-bit tileset. I still haven't finished picking my palette, missing two colors or so.
First try at sidewalk/cobblestone street tiles. Not very good, eh? I'm surprised the river looks ok,it was almost by accident. The brick walls are recycled from some other tileset and look off. I'm rather pleased with my grass and earth, though.
Missing tiles everywhere.
Edit: My grass looks like the snow. Odd fluffy green thing! No remedy to that other than to try and make a grass carpet instead, right?
