how I pick colors for the blog fabric
I go here and I sort of let my eyes just scan and pan across the page, seeing where they naturally want to stumble into. Consider it like a fancy ouiji board. I also consider the existing blogfabric, in case I want to lean toward some continuity. but generally speaking, if the time inbetween posts is short enough, the colors shouldn't differ too widely, or if you're being unnatural.
