EDIT Jan 2nd 2011: Due to the amount of people filling this in, and the fact that I'm going to be on dA very scarcely for a couple of months, I can no longer look at everyone's filled in memes. I'm really sorry! I originally planned to continue looking at everyones, but I just can't keep up at the moment. 
Thank you everyone, once again, for filling the meme in and showing such an interest. I'm glad you're all having fun with this! C:
Feel free to continue linking the memes here though, who knows in a couple of months I might get time to go through the backlog and finally be able to look at everyones work! 
I searched dA for a meme like this but couldn't find one, so I made one myself!
The rules are simple, just do a painting/drawing in each of the boxes using only the colours specified.
Obviously this is more suited to digital art, but there's nothing to say a traditional artist couldn't do it. As long as the colours are similar, i guess.
I recommend downloading the huge version, it's easier to fill in.
My version:

w176 has created her own version here:

EDIT 4: More colour scheme challenges to fill in!
