FWIW, and YMMV…. The easiest front sight for me to see under the different conditions that can happen, is the Tru Glo TFX tritium fiber optic with the white circle. That combination just works easiest for my old eyeballs.
A good gold bead can still work for me if there is some kind of reflecting light.
With enough practice dry and live fire, in different positions, muscle memory can develop and make a BIG difference.
The red ramp & white outline of the old Smith revolvers still works surprisingly well for me, with some light source & that muscle memory.
Night autoloaders have a light, and I also have handhelds.
Kids are out of the house, but the wife still lives here, so I still have to consider one hand being busy with her or doors, leaving the light on the gun as my light source.
motion activated night lights can help….
Dog(s) can be worth their weight in gold.
Darkness isn't only a nighttime thing. Closets, basements, whatever, can also need lighting to confirm what I see.
Again, those TruGlo TFX’s are magic for me, especially on the pistols designed to make it easy to change sights. The TFX model with that white circle on the front sight, nothing else comes close.
just my thoughts….
