IR has a longer wavelength than Blue yet Blue definitely travels further. But yes, warmer colour temperatures penetrate Fog, Smoke better. But in normal conditions, Cooler Whites are more brighter. There's a good reason the Sun is very bright on a clear day. The Sun when setting is still dangerous to look at, but is more dimmer. In short, every Colour has it's purpose.

@@Vinnay94 Blue travels the least far of all the colors. Reed travels the farthest of visible light. And if you don’t believe me, or scientists on the internet, then a red light and a blue light and hold pieces of paper in front of them, keep adding papers until you can’t see the lights anymore. The red light will shine through more papers. It’s the same reason your earlobes glow red and the sunset is red and air traffic lights are red and spotlights all use warmer tones.

@@hunterterrell9930 Yup, that's why we transfer data with longer wavelengths, it can just travel further undisrupted :)

I looked up that green lasers can be seen further. So red does help a lot to keep you hidden in the dark.

Was thinking the same thing, red is not reflected well from green items like uniforms, leaves, grass and it's also at a limit of the human visibility spectrum.

Поэтому светофор красный по вашему. Чтобы быть скрытым от водителей?😊

red

I am interested, please elaborate further. Thank you.

IRREGARDLESS???

Yes, starlight pnv-an night vision was in red, guyscsaw creatures in other dimensions.

@@deanc.5984 But this has nothing to do with normal red light.

I recently purchased a Thermal electro optic…. I can see the true shapes of people and beings walking by…. All I can say is…. They are among us 👽 👹

Infrared doesn't care very much for the color of light necessarily... only the heat from the creation of light. That being said, there is near IR (750 nm to 1300 nm wavelength). The 700 nm range is close to the edge of the color red wavelength. IR also has a medium IR (1300 to 3000 nm wavelength) and far IR (3000 nm to about 1000 microns). Hope that helps. Sorry I did not see your question... YT sometimes does that. :-/

There's also recent research that indicates that blue light at night can disrupt your sleep cycle - blue light will wake you up. Especially if you're sleeping while people are trying to be sneaky around you with blue lights. It is also proven that blue light is responsible for the damage of photoreceptors, and overexposure can cause blindness.

@@Sara-L keep your hand off it, it also causes blindness! I read that somewhere, so it must be true 😜🤯 lol

Not true with the red light distance. If you sit a above a city. You can see the red stop lights go on and off, better than you can see a green light. Or blue. Even at ten miles away. Red is a Long wavelength. Green is shorter. Don't believe me! Sit on a hill above a city or town and see for yourself. (0321) You can see a cigarette cherry from a thousand yards at night.

@@Sara-L It isn't so much blue light, but any light or disturbance can disrupt the sleep cycle. Which is of course common sense but many people don't realize having their lit up clock or TV on does interrupt their sleep.

I drive tugboats night watch. I don't know anything about combat environments, but from what I see out here, red is extremely visible. Even a fairly dim red light is visible for a mile over the water. Orange is behind it, followed by white, then green. Blue seems to travel the worst, but oddly close blue light ruins my night vision, while red has the least effect.
