    Using an RGB LED to Detect Colours

    Hi everyone! I was thinking about a robot that can return a ball and I was looking at this to detect the ball.My queston is, if the ball is lets say red and we're making it run on a white desk, from how far can a sensor like this detect that the color of the ball is different from the rest of the table/floor? So that the robot can go there and "take it"
