Multi coloured light

Wouldn't it be good if you could have one multi coloured light that can change colour? Would the multicoloured light look just like this one?, Sadly this one is just something we made up to test, so it will not be available

The idea is that by using the colours green red and blue, by varying the intensity you can get almost any colour, but unlike ordinary lamps you can not dim a led as you normally would, instead you have to pulse its supply

May be one day some one will put this into production, in the mean time , we can dream cant we?

Since this page has been written (around 2002)  there is now available  RGB led submersible lights (see below)
