Random Properties

Hello.

I am using flash mx 2004 and i have made a scene 10 by 10 pixels with 100 * 1 pixel by 1 pixel square movie clips (MC name: pixel) placed next to each other, understand? I hope so :D.

Basically i would like them to change colour etc when a user presses enter.

under properties there is a bit called Color then there is a drop down box and in here there is a bit called advanced.

If you fiddle around with these setting you can alter the color, brightness, etc of an MC.

Can actionscript alter these so when a user presses enter each induvidual pixels properties changes to something random? thank you.
