Color is weird. I mean, how we choose colors that we work with or wear or whatever is dependent on what kind of mood we are in at the time. How the color makes us feel is as important as what the color actually is. I always thought I was a bluey-green sort of person, but it turns out that I have way more orange in my yarn stash than any other color, so it must appeal to me.
Apparently I like purple a lot, too. Purple always feels good in my hands and, well, everywhere.
But, looking over my Ravelry projects I have supported all the colors equally, except black. I only have one black project.
Black is hard to see, but quite stunning when it is finished. Black is also hard to see texture in, so cables are sorta out, though I remember seeing a black Aran sweater once that was gorgeous. Black is good for lacework, though. Hmmm. I'll try to work more black into my finished goods, but don't worry! It's not because I am depressed!
