This file is sized to print as a 7"x9" full color card. I keep about 12 of these cards on hand for my students to use as resources. They come in handy when discussing works of art, color theory and color mixing.
I recommend printing these on 80# or 100# card stock and then laminating them, so they will be durable for longer use.
The wonderful thing about downloading this file is if some of your cards get lost of ruined, you just have to print more, not order more from a catalog!
