Over the years I've experimented with a number of things to improved visibility under low light woods conditions. That has included factory plain sights made of dull gray steel, and sights of silver. Then I tried various "fluorescent" colors of model airplane enamel paint dabbed on like red, orange, green and white.
For month in / month out year round best compromise I finally settled on "white" as standing out the best under low light woods conditions, and to be specific, a bottle of bright white "hard as nails" ladies fingernail polish is all I've used for a number of years now.
The fluorescent ones which are supposed to have a bit of light gathering ability are really at a disadvantage in the darker woods as there's not enough light at the very best times of the
day...AND...in the beautiful fall woods with all the bright colors, the colored sights didn't contrast and stand out well at all for me to pick them up quickly.
The color white however, is rarely ever seen as a natural background color in the woods when hunting...and the white front sight offered me the best / strongest contrast against backgrounds of dark green vegetation, dark gray and black tree trunks, gray brush limbs, gray squirrel fur, brown deer hair, turkey heads in the spring, etc, etc.
Other things may work as well, it’s just that for me this particular choice not only works fine but is available everywhere, cheap to have a bottle at the house and in the range/gun box, easy to apply with the little applicator, very durable, etc.
And interestingly, many of the OEM replacement front rifle and handgun sights I've seen in catalogs from places like Brownells, have a white insert in them.
