ROY G. BIV (SANTORINI EDITION)

Inspired by @semioccasional ages ago sry
  1. You may think this is brown but it's a red sand beach!
  2. This hostel dog followed me on a 1-hour hike.
  3. Not a lot of green on this island but this lighthouse has some on it.
  4. These clouds are purple, right?
  5. Bonus!
