Instructions in-game, but I'll tell you them here anyway, because you are special. Pick any 2 digit number (10 doesn't really work that well.....just sayin) Then add its digits together.(we'll call it Sum-a) Subtract Sum-a from your original number. Now find the color-corresponding number in the chart. The MAGIC disc will guess you color! Please comment if your color isn't right, Have fun playing!
This was inspired by the Magic Cooking (or something like that) Feel free to remix or try to find out how it works!
