I'm good with any. I do substitute a lot with other companies, but I think most people understand color in terms of the SU names. Maybe in aother year or so it will be time to ask again?
Anyhow I love the time and effort but into the color challanges and wanted to say I'll be happy with whatever. Even if I don't always do the challanges I'm ALWAYS inspired by the color challanges and the galleries.
