What Color Is A Mirror?

Green! Cause I always see glass tables that are greenish on the sides. Or shit turns green when you put a mirror into a mirror, and it looks like it never ends.
 
Weird. I always thought that the sky was blue because it was a reflection of the ocean. Guess not. You learn something new every day
 
captain obvious strikes again.

not really, in handheld pointers that your astronomy teacher uses to point out stars, green is used just because the human eye can see it easiest in low light. in terms of real high powered lasers that you might find on a telescope or in a lab, any of the colors might be used based on its wavelength, efficiency, and crystal dimensions required for its intended purpose.
 
You got that backwards mang, the ocean appears to be blue on a sunny day because it is a reflection of the sky. And on a cloudy day, when it's 'grayer' out the water appears to be more gray.
 
Hold up. I was under the impression that, from the surface, the ocean appears blue-ish due to the prevolence of algae in the top of the water collumn (which would be photosynthesizing less when it's cloudy out and therefore less colorful?). The water appears blue from under the surface (when looking through a mask or something) because blue is the wavelength of visible light that penetrates the deepest into the the water, with red penetrating the least deep. At a certain point in the water collumn, all the visible light except for the blue light has been culled out of the water, so when you open your eyes, blue is the only color light entering your retinas. If what you're saying is true, then water would look blue/gray from the surface but be completely clear when you're inside of it, which anyone who has ever opened their eyes underwater or snorkled or watched animal planet knows isn't the case.
 
the ocean is blue because there is blue light, from the sky, shining through it. if there was a different color light on the water the waters color would change accordingly. it has nothing to do with algae or lights ability to "penetrate" water, at least not on the scale youre talking about. take a colored light or laser pointer and shine it on a clear glass of water and the water will take on the color of the light.

look, a purple light in a pool makes purple water

totally thought it said what color is A Minor - like a musical chord.

somewhat disappointed. i was ready to get really high and have my mind blown. still interesting though
 
Noooooo they're red!!! Haven't you ever seen Star Wars????????

But in all seriousness, it depends on the application. Powerful consumer lasers are green because it's easiest to see. In theory, the most powerful visible light is violet since it has the shortest wavelength.
