Do yellow or orange as an arrow color work better with your colorblindness
Unfortunately, no. Black tends to be the best color contrast for me. Thanks for asking :)
The following is, by far, the best description of what I live with. The only correction I would add is that these colors become perceptible when placed on a neutral background (black or white only. Gray doesn't work well for me). When placed together, these colors blend.
I also cannot distinguish blue from purple unless they are placed on a neutral background.

Dichromacy
Protanopes, deuteranopes, and tritanopes are dichromats; that is, they can match any color they see with some mixture of just two spectral lights (whereas normally humans are trichromats and require three lights). These individuals normally know they have a color vision problem and it can affect their lives on a daily basis. Protanopes and deuteranopes see no perceptible difference between red, orange, yellow, and green. All these colors, that seem so different to the normal viewer, appear to be the same color for this two percent of the population. The terms protanopia, deuteranopia, and tritanopia come from Greek, and literally mean "inability to see (anopia) with the first (prot-), second (deuter-), or third (trit-) [cone]", respectively
The most common question I get is "How can you tell if a traffic signal is red or green?". Easy ... the bottom light is green, the top light is red. If an intersection has a single, flashing light (either for a crosswalk, or stop sign) I have to look for other traffic control signs because I cannot tell the difference between red and yellow lights.
On a random note, I work in the sand & metallurgy lab at the steel mill. There is one test using Methyl Orange that I am incapable of doing simply because I cannot tell the difference in color when using the reagent.
Anyone want to sort my Canada small queens collection?
