About colors
RGB and CMYK models
Have you ever wondered why the world surrounding us appears colored to
our eyes?
Light is electromagnetic waves with wavelengths between about 380 -
780 nm, also called visible rays. The wavelengths of visible rays can be
separated into the rainbow colors violet, indigo, blue, green, yellow, orange,
and red, from the shortest wavelength in order. When all the wavelengths of
the visible rays strike your eye at the same time, white color is perceived.
We see the objects in color because they reflect or transmit visible light of
different wavelengths or frequencies.
