# Allows the user to switch through four colors. Hitting center exits the loop.
# Contrary to the name no I haven't figured out how to nest it or properly exit the loop without ending the program.
# Previously, after the loop, there was a beep and wait block to try preventing a total program exit, but this didn't change anything and still completely ended the loop. I tried adding another loop, but I didn't have time to put anything in the loop to test whether or not it works.
