Russell, the peach and orange are the common colors you will find today on Carnival ships. Many people call the peach, pink, which it is not. The other colors were what was found on the corresponding ships when Carnival first started. Over the years the colors became mixed on all the ships. I believe there is another set of blue sky chips because as you can see in the scan the inserts are different from one set to another and the $1 chip is both a light blue and a dark blue chip.
