What is the most common first color that children recognize? The second?
I don’t think I can answer any better than this website. Vision works on contrast, not individual colors. The first is light-dark contrast, so you could say that infants can see white, black, and grays first. This is probably followed by red-green discrimination and then yellow-blue discrimination.
(answer) We have a WWI aircraft we are recovering with fabric that requires a dark green paint for the wings. This aircraft is flown a lot and displayed to the public outside quite a bit. The problem is that this paint absorbs sunlight heat dramatically which reduces the life of the doped fabric, causing it to shrink prematurely and it is fairly expensive to replace. Would a primer coat of silver dope or white help reduce the absorption of the heat into the fabric under the dark green paint? (answer) Do you know the origin of a measurement called the “flop index”, which is defined as flop index=2.69(L15-L110)^1.11/((L45)^0.86). My Xrite M68II reports this metric, however, X-Rite does not explain the source of this equation. Do you know where I might find the source of this equation, or another good way to mathematically explain the color difference at several angles?
