Can you see red with night vision?
It takes a very low light level sensed by the eyes to produce this chemical called rhodopsin, or visual purple. It is an interesting trait that deep red lights do not trigger the neutralization of the rhodopsin, so astronomers and safety officials use red lights for night lighting to allow night vision to continue.
Why can’t you put your LED lights on red at night?

What’s the most noticeable color?
greenLight travels in waves as wavelengths. Some wavelengths are easier for humans to see, and green is the most visible from a distance. There are receptors in the eye called cones that contain pigments that sense wavelengths which communicate with the brain which colors we see.
What color helps you sleep?

Why do I see shapes when I rub my eyes?

What colour isn’t real?
If color is solely the way physics describes it, the visible spectrum of light waves, then black and white are outcasts and don’t count as true, physical colors. Colors like white and pink are not present in the spectrum because they are the result of our eyes’ mixing wavelengths of light.
What colour does not exist?
So if it doesn’t exist, why can we see it? Again, on the spectrum of elements, all visible colors (and non-visible rays) have specific wavelengths which distinguish them from the other colors on the color wheel. Magenta, because it doesn’t exist on the light spectrum, doesn’t have one.
