Mark - I believe this is everything I need. Thanks! I especially like
you usage of the templateImage which keeps everything easy to work with
and no cleanup needed.

Hi Ray,
This function doesn't involve moving the mouse cursor.
function screenlocColor
put the screenloc into myLoc
add 31 to item 1 of myLoc
add 31 to item 2 of myLoc
put (the screenLoc),myLoc into myRect
export snapshot from rectangle myRect to myPixels as PNG
set the text of the templateImage to myPixels
put char 1 to 4 of the imageData of the templateImage into myPixel
return charToNum(char 2 of myPixel), \
charToNum(char 3 of myPixel),charToNum(char 4 of myPixel)

Anybody know of a function which returns the color of the screen at a
given location? Simply pass it a point and get the color of that pixel,
kind of like a combination of the mouseColor function and the
controlAtScreenLoc function. I'd be happy if it only worked for points
on Livecode stacks. I've tried 'click at loc [myPoint] and then getting
the mouseColor but it doesn't work.
