Yes, glReadPixels, but can slow down the graphics pipe line.
What are you trying to do maybe a better way then with glReadPixels

well im working on an assignment that i have, im supposed to make a simple paint program.. and i thought that i would be really nice to have like a colorful triangle or whatever that i can select the drawing color from.. so if i click on it it would read the pixel color and set it .. http://www.opengl.org/discussion_boards/ubb/smile.gif
