red colour
The red colour of tuna flesh is primarily due to the presence of relatively large amounts of myoglobin, an oxygen-binding protein similar to haemoglobin. In the presence of oxygen, the attractive red oxy-myoglobin is dominant, but will degrade during storage to ultimately form brown metmyoglobin.

Why is tuna not red?
The dark, purplish red color of freshly cut tuna is due to deoxymyoglobin, which in air changes first to bright red oxymyoglobin and then to brown metmyoglobin. Tuna purveyors must therefore hustle to rush their tuna from the boat to the sushi bar while it is still in the red oxymyoglobin stage.
