Talking Re: Black is it really black?

Color is related to the frequency of the light,be it generated by an LED or laser pointer or reflected by an object illuminated under a full spectrum light like white. Remember our sun is about 10,000 degrees at the surface and hotter several million further inside, but it is not white, you go Superman, its sorta yellow.

Black is often defined as the absense of light or the object that does not reflect light. A black body like a lump of coal pretty much adsorbes all light and reflects none, thus is black.

A piece of blackened metal does radiate light at long or low wavelengths that relate to it temperature and can be easily measured with a simple temp gun. We dont see infrared but it is there especially at 904 nm wavelengths which we call OH SHIRT he's got my speed............DAM. Take a blackened object and heat it to about 2000 f and youll see the redish hue due to the radiated light being within out sensory range, and we call it light. Were defective in that if we dont see it we sorta discount its presense or significance, like IR,, UV light and so forth.

For me Black is the appearance of an object that does not reflect light or the absense of light like at night or in the middle of political campaigns. My car is black and the hood is darker, as it does not reflect any light and has a matt finish that does not have a visible sheen. Ie no reflections from the front of my crossfires body.

Like Mick said, Paint it Black. THE END.
