Because it rhymes with dead.

>>Why is the color red used for stop signs, danger signals, and brake

>>lights?

 

I think the major reason has to do with how light gets absorbed in fog,

particulates, haze, etc.

We know that light is scattered (and thus attenuates or gets weaker) as it

travels through a scattering medium composed of small particles.

 

As it turns out, red light is scattered (is weakened) less than other

colors. In fact, of the light spectrum, blue is scattered the most and red

the least.

So I'm not completely wasting my time here. You really do learn something new everyday. Yesterday I learned that vaginas can have teeth, today I learned why red is the danger color. :thumbsup:

 

 

Are you suggesting vagina's should have traffic lights on them?

Why is water blue in a lake and clear in a glass?

Such good questions!

"The ocean looks blue because red, orange and yellow (long wavelength light) are absorbed more strongly by water than is blue (short wavelength light). So when white light from the sun enters the ocean, it is mostly the blue that gets returned."
