clapotis color conundrum

So I've purchased some Kona Superwash Merino, undyed, from which to craft a Clapotis. I can achieve most colors with my dye collection, so now I just have to decide what color to Clapotis with. I already have a Charlotte in purples, so I guess I should stray from my usual base color, or at least mix it up quite a bit with some other shades and hues. I'll likely wear it with either black or earthy tones. I'm considering something in browns and greens, but I'm not sure that I trust my ability to mix brown dye... Suggestions? Links to your favorite variegated yarns?
