what colour the melanin would be?

Melanin is the product of a series of biochemical reactions, each step being controlled by a specific enzyme. If any or some of the enzymes in the terminal end of the pathway are absent, the end product may not be black; it may end up giving a brown pigment. But if all the steps are completed then melanin assumes black colour. The number of melanin molecules per unit area determines the overall colour of the skin or hair.

There are 2 kinds of melanin:

(a) eumelanin - abundant in dark-skinned, dark-haired individuals

There are 2 types of eumelanin: black eumelanin and brown eumelanin. A small amount of black eumelanin in the absence of other pigments causes grey color. A small amount of brown eumelanin in the absence of other pigments causes yellow (blond) color.

(b) pheomelanin - abundant in fair-skinned individuals.

Pheomelanin imparts a pink to red hue and, thus, is found in particularly large quantities in red hair.

I hope this helps...

I think melanin pigment differs from one person to onther

from faint white to deep black and some people havnt that pigment and they are called albinu

red
