> If you're catering to the extremely rare achromats, there's a heap of accessibility options you should be considering first, including braille for blind people.

In the general population, blind people may outnumber achromats, but in the tech worker population, I'd say that relationship is inverse.

An achromat can usually manage to be productive in an office setting, often without alerting others to their condition.

Blind people have it much much harder and thus are less represented at a large tech firm like Microsoft.
