I wounder if any of you consider the color of your metal when setting a gemstone, and if so what colors do you prefer for what stone types?

An example i find very attractive is green stones against yellow gold. For example James "Goldsmith" has used this color combination for his paper knife, al be it enamel rather that stone; http://www.cooksongold.com/forum/alb...achmentid=2278

what would you set with red gold, or white gold?
