cones

What if there were some way to selectively stimulate just the M cones, or to prevent the L cones from being activated?

The idea is to stimulate all 3 types of cones and the rods in the same proportion as daylight does.

Medium cones are responsible for seeing the medium λEMS peak at green, where the Short cones kick in for short λEMS, and they peak at blue.

A color is just the subjective sensation we get because of different balances of stimulation between our short, medium and long wave cones.

More cones generally means fewer rods, which means poorer night vision.

Meanwhile reptiles, birds, amphibians, insects have 4 types of cones and much better color vision than us.

So you can just put a couple of cones across a highway and stop all traffic for a few hours?

At least two cones are usually stimulated, and often all three, even by monochromatic light.

Primates are unusual among mammals in having 3 types of cones and better color vision.

Explanatory note: Most humans have three types of color receptive cones; a few have four.

Really what you need to do is match the wavelenghts that our rods and cones in our eyes are most sensitive to.

It is a common misconception that long cones are mostly sensitive to red.

The reason why I call RGB "wrong" is because the L and M cones both have peak sensitivities to greenish light.

There's way to many "apps" that don't deserve to be anything more than a website and I take a hard line when it cones to my privacy.

Long cones are responsible for seeing long wavelengths ("λ") of the visible electromagnetic spectre ("EMS") are going towards Red and peak there before fading into infra-red.

Our eyes have three types of cones, call them L, M, and S (you might think "RGB" but it's really not, but that's not a bad lie to believe).
