Michaels has some of those that come in a tube for a dollar. I would be careful with them though, if someone breaks one, it will stain everything it touches and you wouldn't want the actual liquids on the cake.
If you can't get the Americolors, Wilton's Rose, Leaf green and Lemon yellow are pretty bright too.
