pixel colour on screen

[cjstuttle at hotmail.com]

Could anyone help me, I'm a python noob and need some help. im trying
to find some code that will, given a screen co-ordinate, will give me
the colour of that pixel in RGB. i have found a lot about getting the
pixel colour from a picture file with a given co-ordinate, but is it
possible to do it from the whole screen output regardless what
application the selected pixel is in?

any help would be help.

thanks, Chris
