For example, the use of a white background with black text is an example of a common default color scheme in web design. Color schemes are logical combinations of colors on the color wheel. Color schemes are used to create style and appeal.

The color of chemicals is a physical property of chemicals that in most cases comes from the excitation of electrons due to an absorption of energy performed by the chemical. What is seen by the eye is not the color absorbed, but the complementary color from the removal of the absorbed wavelengths.This spectral perspective was first noted in atomic spectroscopy.

RYB (an abbreviation of red–yellow–blue) is a subtractive color model used in art and applied design in which red, yellow, and blue pigments are considered primary colors. Under traditional color theory, (which some artists see as the “correct theory” whilst others use modern color theory [cym] instead) this set of primary colors was advocated by Moses Harris, Michel …

In offset printing, a spot color or solid color is any color generated by an ink (pure or mixed) that is printed using a single run, whereas a process color is produced by printing a series of dots of different colors..
