Please click
http://2move.me.uk/JustBackGrounds.html to see a web page changing background colour every two seconds. I have done that with dhtml and have used key words for colours instead of colour codes. Dhtml recognises upto 18 colour key words. every one welcome to use the script. It is a freeware. The script can be expanded to include all colours, over 1500.
