I stumbled across these two books at the library last week and am so glad I did. They're wonderful! Sweet and colorful and so much more than just color and shape books. Both are written by Roseanne Thong and illustrated by Grace Lin.
From Red is a Dragon:Red are melons cool and sweet Red are lychees a summer treat
From Round is a Mooncake:Rectangles are inking stones Paintbrush racks and mobile phonesSince I've fallen in love with Grace Lin's illustrations, I did a little search on her. Turns out she's illustrated (and written!) quite a lot. There's a great interview and bio here at Seven Impossible Things Before Breakfast that also describes a number of her other books. Very worth checking out. Look for the picture of Lissy's Friends -- that's the book I want to find next!
