From the manufacturer:
StarBrite Coral Pink is a bright, warm pink. This vibrant pink works well as a mid-tone when setting up for a full spectrum tattoo or as a highlight to make pieces stand out.
Coral Pink works great as a versatility color. It can be mixed with Blood Clot to give you a more natural fleshy shade or Tribal Black to create a very warm, greyish pink.
This color works well with other reds, oranges, pinks and yellows as well.
