A CSS Colour Sampler

I was doing a bit of design hacking earlier, and searched the internet (in vain) for a CSS sampler. You know the concept - you type in a hex code, and it tells you what colour you’re using. Well, that’s the second time I’ve looked, so I made my own, as you do. Found here, it does exactly what it says on the (not quite) tin - shows you a sample of any css colour. One huge block that’s fairly unmissable. I might make the code downloadable at some point - it’s really not that complex.

Anyhow, any feedback on it would be appreciated :D
