I've bee wondering this for ages and havnt found an answer. I was wondereing how colours are projected in the monitor? I know its done digitally, but how does it actually produce the colour?

What kind of monitor is it?

just a standard CFT, but i was wondering how the scrren produces colours? is there a physicial colour element inside?

electrons are excited into certian color wavlengths and strike the screen producing the color

Red, blue and green "lamps" sends out color. The monitor mixes those colors inte the one you see. If you have a small drop of water on the screen you can see those "lamps".

All you ever needed to know. It's a little more complex than "lamps" - they use cathode ray tubes (i.e. a beam of electrons).

That's why I used ", cause I didn't know exactly what it was =). Thank you for telling.

But a beam of electrons... can we see that? Don't you mean photons? =/

The electrons hit the screen, coated with phosphor which glows.

Have a look at this. Phospherous material on the screen.
