I've had several eye surgeries resulting in a bit of vision impairment. One of the side effects is partial color blindness. My eye doctor recommended changing to yellow golf balls as they are easier for me to see.
On another note at one time my golf league partner was fully color blind. I took cruel delight tossing him a red tee so he couldn't catch it just to watch him try to find it against the green grass. But I always bought the first round to make up for it. Those were shining times.
Have fun and hit em straight,
