daltonism

Certain authorities on art are said to regard the great Montalbanais as a victim of daltonism—in other words, colour-blind!

Daltonism, dal′ton-izm, n. colour-blindness: inability to distinguish certain colours.

An interesting example is the common type of color blindness known as Daltonism.

Colour-blindness or Daltonism has been recorded (Horner) through the males only of seven generations.

The diseases known as Daltonism or colour-blindness, and hmophilia or the bleeding disease, are certainly hereditary.
