* [PMA] Amount of Pheomelanin (white - red)

* [BMA] Amount of black Eumelanin (white - black)

EMA gene is the same as for [[eye colour]], so that dark brown eyes can't appear with light hair (brown and amber eyes still can, by a combination of low EMA level and high STP levels in eye colourisation)

Melanin levels (only two of those can be on "high" at once, one from the father and one from the mother):

  • Black Eumelanin (white to black)
  • Brown Eumelanin (white to yellowish brown)
  • Pheomelanin (white to red)

Pseudo-genes encoding this:

  • [BTB] Black-to-Brown Eumelanin balance (black - brown - yellowish brown)
  • [EMA] Amount of Eumelanin (white - fully coloured)
  • [PMA] Amount of Pheomelanin (white - red)
  • [BMA] Amount of black Eumelanin (white - black)

EMA gene is the same as for eye colour, so that dark brown eyes can't appear with light hair (brown and amber eyes still can, by a combination of low EMA level and high STP levels in eye colourisation)

Typical combinations:

  • Black Eumelanin only -> Black
  • Brown Eumelanin only -> Brown
  • Pheomelanin only -> Red
  • Black Eumelanin & Pheomelanin -> Chestnut Brown
  • Brown Eumelanin & Pheomelanin -> Auburn
  • low amount of all -> Blonde
  • negligable amount of all -> White
