Short article describes the theory of color associated with the spectrum elektromagnetik.

The theory of color, including one branch in the knowledge that covers all aspects of how people view and mengintepretasikan color. In this article we will only know the theory of color briefly.

If you are interested in knowing more about the theory of color, there are several websites out there who will discuss this topic with more details.

If we talk about color, we certainly refer to the things that are visible, related to the eye, and the spectrum (part of the visible spectrum elektromagnetik by the human eye).

Try to see the following:

* Red: part of the visible spectrum with a wavelength between 630-760 nanometer.

* Color orange: part of the visible spectrum with a wavelength between 585-620 nanometer.

* Yellow: part of the visible spectrum with a wavelength between 565-590 nanometer.

* Green: part of the visible spectrum with a wavelength between 520-570 nanometer.

* Color blue: part of the visible spectrum with a wavelength between 420-490 nanometer.

* Color nila: part of the visible spectrum with a wavelength between 420-440 nanometer.
* Color Purple: part of the visible spectrum with a wavelength between 380-420 nanometer.

Wavelength is measured in units of nanometer (nm). One nanometer is the same as the one by one billion meters.

It is interesting here is the human eye is able to distinguish each with a different color only a few hundred nanometer course.
