I created this poster option to be used as an bonus giveaway item at merch booths with any merch purchase. The band wanted to create a concept based on secret messages and cryptography to go with their new logo. I created a hidden message idea using colors, and loosely based on eye tests for color-blindness and on 70's cereal box decoder games. If you block out certain colors you can see different messages in this picture
