Probably beta-carotene. This is the same compound that is found in carrots and the substance that give flamingos their color.

The color of a scud depends on the age of the individual, its diet and the temperature of its surroundings.

The Orange color in the scud is eggs. When scuds get pregnant, they carry the eggs under their belly giving off the Orange look.

Scuds with an orange dot in the center are females with eggs. Solid orange scuds are dead.

I remember reading this somewhere. I think it was in one of Earnest Schweibert's or Gary Borger's " Designing Trout Flies ". Got me wondering. I'll look it up and let you know.
