Color

Color is an extensive physical property of matter, meaning that

The Main Idea

Color is an extensive physical property of matter, in that it can be measured differently by two viewers of the same object. This can also be seen in if a large amount of matter is present as opposed to a small amount of the same matter, the color viewed by the same viewer may be altered. The physical color seen and interpreted by a viewer is subject to the brain and the eyes of the individual. The object itself absorbs a certain amount of light and reflects the rest. The wavelength of light that is reflected off the surface of the object is interpreted in the eye as a specific color.

A Mathematical Model

Each color has a spectrum of wavelengths of light associated with it. The range of colors we are conditioned to seeing regularly are in the wavelength range of 400-650nm. Matter can technically reflect wavelengths above and below this, they can just not be seen with the naked eye. These wavelenghts for colors are listed below:

A car takes 3 hours to make a 230-mile trip from Point A to Point B.

Color	Wavelength (nm)
Violet	400
Indigo	445
Blue	475
Green	510
Yellow	570
Orange	590
Red	650

Violet - 400nm Indigo - 445nm Blue - 475nm Green - 510nm Yellow - 570nm Orange - 590 nm Red - 650 nm
