Answered: Painting Vex IQ for ringmaster

The team I am trying to help wants to color(paint) some of the Vex Components. (They plan to color them using Acrylic paint) so that they can be identified by the color sensor.

Example - Team wants to paint 6 beams with 6 different colors, and use a color sensor to detect the color in front. This will be part of the robot.

Is this legal - or it will be against rule R13

Yes, this is legal.
