We had orange lines on the field today. The AR kept crossing the line onto the field- seemed strange.
He then tells us he is color blind and can't see the lines. We thought he was joking but he assured us he was serious.

I can believe it -- especially if he has red/green colorblindness, which apparently affects about 5 percent of the male population to different levels. That's why some places (especially in eastern Canada) have different shapes for traffic signals -- square for red, diamond for yellow, round for green.

Could that affect someone's ability to tell red from blue? Just curious...

From what I understand (and that's very limited) I don't think so. Reds and greens come across as varying shades of gray, but shades of blue are not similarly affected.
If anyone knows more about this please chime in -- most of my knowledge comes from working with a couple of people who have this issue.

Protanopia is a severe type of color vision deficiency caused by the complete absence of red retinal photoreceptors. It is a form of dichromatism in which red appears dark. It is hereditary, sex-linked, and present in 1% of males. This could explain this AR's inability to distinguish red from blue or black (darker colors).
