I'm not sure if that's even possible, but why on earth would you want to do that?

use the colour select tool and click on the pixel you want, then click on the foreground/background colour tool to get details of the new foreground colour. It's in html format, so you'll need to convert to whatever language you are using.

Best thing I could think of is write an external C/C++program that takes coordinates as an arguments and prints pixel color on stdout.

This C/C++ program may require to use XLib or whatever window manager OS is using.
