This is easily done through using the imagecolorat function.

You must pass as parameters the image resource, and the x
and y co-ordinates you want to find the color of, for
instance:

$rgb = imagecolorat($im, 5, 10);

Will get a reference to the colour used at 5,10 (X,Y) on
the image.

Depending on the version of the GD library you are using
and the type of image, you may experience different return
values
