This graph came from a study on animal vision , Shadow Ace posted excerpts from it at the Bow Hunting forum , it should give you a rough idea of how they see .



Just because they can see a given color doesn't mean that the perceive it the same way we do , according to the study they can see blaze orange , just not the same way that we do since they have reduced perception of red compared to us . To them it would probably look like a grey shade with a slight yellowish tint . I had one look dead at my blaze cap last year without blinking , it must have blended into the background with the other yellows he was seeing .
