Cache not at posted coords but you will need to visit to solve. This is a quick puzzle that will take you to a mural that I have drove past many times and always found interesting. There is no reason to armchair solve this so I am going to skip a certitude on this puzzle and say just go to the field to solve. The cache is very close to the posted coords.
I have made all the demons eyes gray. You will need to look into each demon's eye and find out the color to get the coords.
Demon #1
Demon #2
Demon #3
Demon #4
Demon #5
N 37° 49.ABC W 122° 17.CDE
Demon #1 = A Red=1, Green=5, Yellow=7
Demon #2 = B Blue=1, Yellow=4, Red=6
Demon #3 = C Red=0, Green=3, Blue=8
Demon #4 = D Green=2, Blue=5, Yellow=8
Demon #5 = E Red=2, Green=4, Yellow=9
Hope you enjoy the puzzle and remember to take a demon home with you.
