Click on the color that you favor the most out of the three choices (in this order: red, green, blue). The last one that is purple is actually other in case you don't like the other colors (it is other. EX: It could mean that your favorite color is grey.) MAKE SURE TO ONLY CLICK ON THE COLOR THING ONCE. It glitches sometimes...
I used the cloud data to give people a survey that they would be able to see the numbers of actual people. Of course you can abuse it, but I'd rather not.
