[Chad Brewer] "Am I color blind? "
ummm...
we cannot answer that
However if your male there is something like a 1 in 4 chance you have some degree of color blindness with a full 7%-10% of ALL men in North America being completely deficient in the Red/Green part of the color spectrum while women only show a 0.4% rate in the same demographic.
"I know exactly what 4:4:4 is. What is 4444? "
RGB with Alpha - ProRes alpha is up to 16 bit. (65,536 levels of grey)
and I am betting you can't see that many levels of grey either.
