What color combinations go good with sea foam green?

I think dark purple or dark gray would go well with it. Even White might be nice, but that could look tacky. Are you using metals? If you are, I'd go with silver, I always think silver goes well with sea-foam green stones, etc.

for a more reserved piece, I'd stick to an analogous color scheme - so other blues and greens. But if you're looking to make something that makes more of a statement, I'd go complementary (with an yelloworange) or perhaps even triadic for more drama (with a redviolet and a yelloworange). I agree with the silver suggestion as well - metals tend to be more visually balanced when all the materials used are either cool (as in your case) or warm. Hope this helps, good luck with it.

Even if I tell you to use grass green, you will end up thinking of a different sort of green 'cause the grass here is different than over there and we see colors differently and it would just be wrong for my to unintentionally mislead you. SO This will help you greatly. http://kuler.adobe.com/ Just search for "sea foam", "green", "sea", anything, and see the results yourself and you be the judge of the colors that strike to you as eye candy potential. Hope this helps. KK
