This was my first reaction, and I’ve used a slew of web color tools, going back before colorlovers

I concur... I'm a developer not a designer, what am I looking at besides a nice gradient of colours... how do I use this tool?

Yeah I'm a dev with bad color taste (i.e. backend engineer...)

It would be nice if it said..use this color for acknowledge font, warning font, background, menu...etc...
