Superb Web Developer Aid site

Anyone who spends a long time designing websites will love Milov’s fantastic subdomain idea. He’s created a simple script that has made a different website for every hex and rgb colour. Simply pick a colour such as bright pink (ff00c1 in hex code) and go to the sub domain for it to see the result ie: http://ff00c1.milov.nl. Alternatively, you can try the rgb code or some real names (such as orange.milov.nl) and it will fill your screen with the appropriate colour letting you see what the colout will actually look like on screen.
