This is a color scheme card that can be used for the Color Coordination Examination. The New Color Scheme Card 199a is sufficient for exam preparation, but instructors can use it to create whiteboard displays, arrange colors randomly for study, etc. If you need a lot of them, how about this one? I have others, so I'm selling this one. It has been opened, but it's unused and the cards haven't been cut out. - Product Name: New Color Scheme Card 199c - Contents: 24 color cards Thank you for looking.
