Eye colour

Contributions to the eye colour, using the CMYK colour space if simulated on the computer:

• Stroma pigmentation
  • transparent to dark brown (Melanin content)
  • transparent to yellowish
• Stroma dispersion type
  • blue to milky-white
• Ephitelial cell layer
  • Either there (then it is black, but appears dark grey to silvery-grey due to the scattered light entering at oblique angles and getting reflected often), or not (albinism; then it is transparent, and the background appears blood-red from the colour of the retina).
