When I still worked for our state Dept of Fire Services, I was told by our purchasing supervisor, who was a severe diabetic, that the
color blind cannot see the bright red orange, but can see the lime yellow. Therefore, when buying vests, etc we always got the lime
yellow or lime yellow striping.
If anyone here can correct me that is fine, just giving the parameters I had to work with. To be fair, the "human" is wearing a very low-budget
safety vest, with very little reflective trim, probably would not meet any US-OSHA standard. Our little cat however...
Love to get one of those for our "tuxedo"
