I always have a difficult time choosing color schemes and I think I often end up overloading my designs with color because there's "just something missing." Today I realized that part of the problem is that I often overlook using black and white as a choice. I use Kuler and Color Scheme Designer a lot (and have used various others over the years), but I've yet to see one actually incorporate black, white, and/or gray into the color wheel/harmony and, as a result, none of them would help me find a color scheme like this:
Ideally, I'd like to find a tool that does that (preferably free for personal use). I will also accept strategies for using the tools I already use to incorporate black and white more easily.
