I loved this paint palette in House Beautiful that came in the mail yesterday - normally I don't particularly like the paint choices in HB but this was amazing. I can't seem to find this online on their site but will site it here nevertheless (House Beautiful). I did a post earlier last year on color found on a rainbow trout which is a similar idea - we don't find many scarab beetles in upstate New York.
If anyone finds a creature you would like me to extract colors from, please send them to me! I would love to give it shot - it could be anything from a pet to something you found in a stream.
