what btg3 said
no different than repainting a wall in your house with bright colors, that white undercoat cannot be overrated
me most liked the blaze orange enamel, too
but have cycled back around to factory unpainted black (deep blued) for target shooting
for DA offhand shooting in sunlight, fiber optic fronts beat (almost) any paint, has to be done to be believed.. but no gain absent UV sunlight, not a great thing for "casual wear"
PS
if Millett ever sells their secret blaze orange paint formula, get some, never saw anything like it in sunlight, better than fiber optics, no "fuzzy"
studies stuff - no color beats bright chartreuse over a wider RANGE of lighting (laser people finally caught onto that, they could have just asked a bass pro wannabe)
but NO color beats black in real low light, absent chemical/electrical/radioactive decay enhancement
never was anything wrong with 'deep blue'
never was anything right with bare stainless sights
what Drail said, true also, red is worst choice, closest to black in the color spectrum, but not as black as black
