Irish moss, or Chondrus crispus, contains a pigment known as phycoerythrin, which gives it a reddish hue. This pigment is a type of phycobilin, which helps the algae absorb light for photosynthesis, particularly in deeper water where sunlight is limited. Additionally, Irish moss also contains other pigments such as chlorophyll, which contributes to its greenish tones.
