Q:Information:  - Color (American English) or colour (Commonwealth English) is the characteristic of human visual perception described through color "categories", with names such as red, yellow, purple, or bronze.

Color categories and physical specifications of color are associated with objects through the wavelength of the light that is reflected from them. This reflection is governed by the object's physical properties such as light absorption, emission spectra, etc. Human trichromacy is the basis for all modern color spaces that assign colors numerical coordinates and associate corresponding distances between colors.  - Vincent Willem van Gogh (30 March 185329 July 1890) was a Dutch Post-Impressionist painter who is among the most famous and influential figures in the history of Western art.
