Puzzle:
Hidden in the colored text below are eight questions. Answering the questions will give you the final cache coordinates.
But first you need to decrypt the questions. Hint #1: words in the same color follow the same decryption pattern. So all of the blue words use the same cipher, all the green words use the same cipher, etc. Hint #2: one of the words in the first question is "atomic".
You can validate your puzzle solution with certitude.
