Index of color-related articles

This page is an index of articles related to the topic of color and its various aspects in science, art, culture, and technology. Colors are an integral part of our lives, influencing mood, communication, and even decisions. This index aims to provide a comprehensive guide to understanding colors, their meanings, and their applications.

A

• Additive color - A color model that describes the process of creating color by mixing a number of different light colors, with primary colors typically being red, green, and blue.
• Aesthetic of color - The study and application of color theory in art and design, focusing on the creation of pleasing and effective color schemes.

B

• Basic color terms - The set of color names that are commonly accepted within a culture as basic descriptors of color.
• Bioluminescence - The production and emission of light by a living organism, often resulting in vibrant colors.

C

• Chromatography - A method for separating mixtures into their components, which can be used to analyze colors in substances.
• Color blindness - A condition in which a person's perception of colors is different from normal due to genetic or acquired reasons.
• Color constancy - The feature of the human color perception system that ensures that the perceived color of objects remains relatively constant under varying illumination conditions.
• Color psychology - The study of hues as a determinant of human behavior and emotions.
• Color space - A specific organization of colors, which helps in the reproduction of color in physical or digital realms.
• Color theory - The body of practical guidance to color mixing and the visual effects of specific color combinations.
• Color vision - The ability of organisms to distinguish objects based on the wavelengths of the light they reflect, emit, or transmit.
• Color wheel - A circular diagram of colors used to show relationships between colors.

D

• Dichromacy - A form of color vision deficiency in which one of the three basic color mechanisms is absent or not functioning.

E

• Electromagnetic spectrum - The range of all types of electromagnetic radiation, including visible light, which is responsible for color perception.

F

• Fluorescence - The emission of light by a substance that has absorbed light or other electromagnetic radiation, often creating bright colors.

G

• Gamut - The subset of colors that can be accurately represented in a given circumstance, such as within a color space or by a certain output device.

H

• Hue - One of the main properties of a color, defined technically as the degree to which a stimulus can be described as similar to or different from stimuli that are described as red, green, blue, and yellow.

I

• Iridescence - The phenomenon of certain surfaces that appear to gradually change color as the angle of view or the angle of illumination changes.

L

• Lightness (color) - The brightness of a color, which varies with its saturation level and under different lighting conditions.

M

• Metamerism (color) - The phenomenon when colors match under one lighting condition but not when the lighting changes.

O

• Opacity (optics) - The measure of impenetrability to electromagnetic or other kinds of radiation, especially visible light.

P

• Pantone - A proprietary color space used in a variety of industries, primarily printing, though sometimes in the manufacture of colored paint, fabric, and plastics.
• Pigment - A material that changes the color of reflected or transmitted light as the result of wavelength-selective absorption.
• Primary color - A set of colors that can be combined to make a useful range of colors. For additive combination of colors, as in overlapping projected lights or in computer monitors, the primary colors normally used are red, green, and blue.

R

• RGB color model - An additive color model in which red, green, and blue light are added together in various ways to reproduce a broad array of colors.

S

• Saturation (color theory) - The intensity of a specific hue.
• Spectral color - A color that is evoked by a single wavelength of light in the visible spectrum.

T

• Tint, shade, and tone - Terms in color theory that describe a base color modified by the addition of black, white, or both.
• Trichromacy - Normal color vision that uses three types of light cones, sensitive to three bands of wavelength.

V

• Value (color) - The lightness or darkness of a color.

W

• Wavelength - The spatial period of a periodic wave—the distance over which the wave's shape repeats.
