Is there a scientific reason for why Yellow appear brighter than other colors? When you look at the color palette of Yellow, you'll only see bright shades, in fact you could argue that even dark Yellow hues can appear brighter than Red

because it's a mix of the two colors our eyes are most sensitive to (red and green)

Talking out of my ass here, but this is my guess. We have three cones in our eye for detecting color. They require some count of photons to be stimulated (i.e., see the color which is why we can't see biophotons despite them being in the visible spectrum).

Yellow is the combination of red and green which is a narrow range of wavelengths. Meaning there is a double counting of photons (equal mixing of red and green) to see it. So to see yellow you must receive twice the photons which is twice the intensity leading to twice the brightness. And because this is a narrow window it'll always be perceived as brighter than any other secondary color.

Yellow also looks brighter on many screens for the same reason that cyan and magenta look brighter than solid red, green, or blue - you're getting light from two subpixels instead of one.

I thought the human eye was most sensitive to green, hence it's use in stop lights and older night vision technology

It's gonna depend on the screen - a lot of modern OLEDs don't drive the green subpixels as hard. Blowing out green is more an LCD problem, because LCDs don't have fine control over subpixel brightness (and an equivalent brightness green subpixel is seen as brighter than red or blue subpixels).

I remember as a kid pondering what a dark yellow would look like. Then playing with higher-bit computers I just toned the intensity down.
Just looked like dark brownish orange.

Well, if that's the angle you want to take, then obviously the human eye is most sensitive to blue because it's the easiest wavelength to cause damage with.

It's kinda ironic how a color we perceive as intense like Red is actually the most chill color for our eyes

eye=25%red, 25%blue, 50% green, therefore:

And you would be correct. The l axis represents perceived brightness.

Would be nice if I attached the image. Anyways, the green primary itself is the perceived brightest of the three colors in the tristimulus system, and yellow acts as the additive combo of green and red light in the frequency domain.

Because it best contrasts with black. Black is dark, ergo yellow is bright.

Some does, some doesn't. If it does, it's probably fluorescent paint.
