Apart from inheritance, what else can cause color deficiency?

Eye Doctor Bay Area | Cataract Surgery Union City | Laser Ey...
Color Vision deficiency could be acquired too. Certain drugs prescribed for arthritis, depression, heart disease, high blood pressure, diabetes, multiple sclerosis, and some liver diseases can significantly affect color vision either temporarily or permanently. Continued use of aspirin can also alter color perception. Excessive use of tobacco and alcohol can have similar effects. Many industrial chemicals can permanently alter your color vision.

How is color deficiency detected?

Santa Fe Vision - Eye FAQ
People who are color deficient are generally unaware of their condition. They assume that everyone sees things the way they do. As a result, a complete optometric examination, including a test for color vision, is recommended. The test for color deficiency is a relatively simple one, typically involving the viewing of a series of colored designs. The designs have been created in such a way that a person with normal color vision can see certain figures in the designs.

How does the color inheritance work in the Newfoundland?

Newf FAQ
The Solid Black is dominant, or BB. The Landseer is recessive to the solid black, or bb, and is the result of the piebald gene, which places the self-color on a white background. Solid Bronze is recessive to black, and the Solid Gray is a dilute of black. Care must be taken when matching dogs with recessive genes, as the piebald gene will result in a solid color and white dog. Where the solid color is black, the Landseer results, which is a color allowed by the standard.

Alright, so what is the nitty gritty on coat color inheritance?

Labrador Retriever Rescue of North Texas_FAQ
Two sets of genes, not one, control a Lab's coloration. One set of genes controls whether the Lab will be dark (either black or chocolate) or light (yellow). Dark is dominant over light. Thus a Lab whose genotype is EE (homozygous dominant) or Ee (heterozygous) will be dark; only Labs that are ee (homozygous recessive) can be light. The second set of genes only come into play if the Lab is dark (either EE or Ee).
