Can you think of any well done websites with high contrast designs that aren't just black text on a white background? I was thinking the same thing but I couldn't think of any good examples off the top of my head--and to me that's a bit of a let down because all this time I've thought the text and style you use on your website can be an identifier of your brand or website. I mean if I could clearly read a site written in dark purple or something, I'd remember that.
