I have been trying to do this for a couple of days (off & on) now and thanks to Angela I think it is going to work.
Stampin' Up! now has a printable color combinations chart that you can download and print at home for lots of color combos with the new In Colors. Click Here to download this. It is 4 pages of options for using the In Colors. If you can't print in color you can print it in Black & White and punch out the colors from cardstock and glue them on (the 3/4 inch circle punch should be the right size).
Hopefully this link works, if not let me know and I will e-mail it to you.
Edited to say "yea, I just tried it and it works". Thanks Angela.
