I was reading http://perlabra.typepad.com/ and heard about this site looking for artwork, http://www.artforautism.co.uk/ The only restriction was that it be black and white plus one color from their provided color palette. Oh and it also need to include of fun fact. So I guess it's two restrictions.
I'm not one to pass up a limited palette.
Blue is my favorite color so I picked that. I knew I wanted to do an animal and I had been brain storming animals that are black for something else I'm working on. The other requirement for the piece is that you include a fun fact. So I started looking up facts and found these two. It kind of lent it's self to showing the birds swimming and that way I could use the blue nicely.
