White is the lightest color [2] and is achromatic (having no chroma).It is the color of objects such as snow, chalk, and milk, and is the opposite of black.White objects fully reflect and scatter all the visible wavelengths of light.
A dispersive prism can be used to break white light up into its constituent spectral colors (the colors of the rainbow) to form a spectrum as described in the following section. Other types of prisms noted below can be used to reflect light, or to split light into components with different polarizations.
The spectrum does not contain all the colors that the human visual system can distinguish. Unsaturated colors such as pink, or purple variations like magenta, for example, are absent because they can only be made from a mix of multiple wavelengths. Colors containing only one wavelength are also called pure colors or spectral colors. [8] [9]
Generally, longer wavelengths (red) undergo a smaller deviation than shorter wavelengths (blue). The dispersion of white light into colors by a prism led Sir Isaac Newton to conclude that white light consisted of a mixture of different colors. Triangular prisms are the most common type of dispersive prism.
White is the lightest tint and a balanced combination of all the colors of the visible light spectrum, or of a pair of complementary colors, or of three or more colors, such as additive primary colors. It is a neutral or achromatic (without color) color, like black and gray
“The color of purity, white is the very essence of projecting a clean and ordered environment,” says Patrick O’Donnell, color expert and Farrow & Ball’s brand ambassador.
Choosing the perfect shade of white can be tricky. Our guide to the 14 best white paint colors offers expert advice for selecting the right tone for your space.
The different color response of different devices can be problematic if not properly managed. For color information stored and transferred in digital form, color management techniques, such as those based on ICC profiles, can help to avoid distortions of the reproduced colors. Color management does not circumvent the gamut limitations of ...
