Color Color Color (American English), or colour (Commonwealth English), is the characteristic of human visual perception described through color "categories", with names such as red, orange, yellow, green, blue, or purple. This perception of color derives from the stimulation of cone cells in the human eye by electromagnetic radiation in the visible spectrum. 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. By defining a color space, colors can be identified numerically
Orange (colour) Winslow Homer brightened his palette with vivid oranges. In France painters took orange in an entirely different direction. In 1872 Claude Monet painted "Impression, Sunrise", a tiny orange sun and some orange light reflected on the clouds and water in the centre of a hazy blue landscape. This painting gave its name to the impressionist movement. Orange became an important colour for all the impressionist painters. They all had studied the recent books on colour theory, and they know that orange placed next to azure blue made both colours much brighter. Auguste Renoir painted boats with stripes of chrome orange
