Of course, true achromatopsia is ridiculously rare. With red/green (two types) and blue/yellow (very rare)
colour deficiencies being more common.
That is, of course, unless he(?) happens to be Pingelapese.
CO poisoning can cause achromatopsia, but usually leads to death instead. In addition, people with true achromatopsia generally have a visual acuity of 20/100 to 20/200 (w/normal being accepted at 20/20). This means most are legally blind.
Why you ask, because they are either missing or have non-functioning cone cells in their retinas, which provide both visual acuity and colour vision.
So, if this is the case, and our "lord of the horse" is indeed inflicted with this genetic disorder, then you are suggesting he be fired or transfered because of this handicap - a sad day indeed.
On the other hand, I want some different colour horses, so: hire the man out to the military - achromatopsics are great at picking out camouflaged vehicles as they aren't tricked by camo - the outline of a tank just sticks out like a sore thumb.
