A name without a clear source
Pearl Aqua with the code #88D8C0 was listed in the 2015 Wikipedia list of colors N to Z, but that entry gave no source. The name sounds like a Crayola crayon. Crayola's 1997 Pearl Brite set did have one called Aqua Pearl, yet Wikipedia now gives it a bluer code, #5FBED7. So treat #88D8C0 as a name from color lists, not an official crayon value.
How it looks
It is a light, minty blue green. Medium aquamarine is a little deeper, and aquamarine is brighter.
