Verified step by step guidance1
Step 1: Understand the context of the question. Melanin is a pigment produced by the body that determines the color of skin, hair, and eyes. There are different types of melanin, each with distinct characteristics and colors.
Step 2: Review the types of melanin. The two main types are eumelanin and pheomelanin. Eumelanin is responsible for brown to black pigmentation, while pheomelanin contributes to red to yellow pigmentation.
Step 3: Eliminate incorrect options. Carotene is a pigment found in plants and contributes to orange coloration in humans but is not a type of melanin. Melatonin is a hormone that regulates sleep and is unrelated to pigmentation.
Step 4: Focus on the correct type of melanin. Based on the description of red to yellow pigmentation, pheomelanin is the correct answer.
Step 5: Confirm your understanding by associating pheomelanin with its role in pigmentation, particularly in individuals with lighter hair colors like red or blonde.
