Use the arrows to move the ballerina. She should tell you what color she's on.
I thought I understood how to use the sensing blocks, but during a first attempt, I wasn't able to program the response I wanted. I looked at the inside of many projects to see if I was writing my code correctly and found that people used the sensing blocks in different ways--some had a direct response when the color was touched and others had a message sent when the color was touched. When selecting the color to get a response, I was very careful to use the same numbers in all color, saturation, and brightness. I'm still struggling! Can anyone offer suggestions? Thanks!!
