Lüscher color test. The Lüscher color test is a psychological test invented by Max Lüscher in Basel, Switzerland, first published in 1947 in German and first translated to English in 1969. The simplest form of the test instructs a subject to order a series of 8 colors in order of preference. This test claims that the order of preference can ...
Color can carry a specific meaning. Color meaning is either based in learned meaning or biologically innate meaning. The perception of a color causes evaluation automatically by the person perceiving. The evaluation process forces color-motivated behavior. Color usually exerts its influence automatically.
Color symbolism in art, literature, and anthropology refers to the use of color as a symbol in various cultures and in storytelling. There is great diversity in the use of colors and their associations between cultures [1] and even within the same culture in different time periods. [2] The same color may have very different associations within ...
Color charge is a property of quarks and gluons that is related to the particles' strong interactions in the theory of quantum chromodynamics (QCD). Like electric charge, it determines how quarks and gluons interact through the strong force; however, rather than there being only positive and negative charges, there are three "charges", commonly called red, green, and blue.
Young–Helmholtz theory. Thomas Young and Hermann von Helmholtz assumed that the eye's retina consists of three different kinds of light receptors for red, green and blue. The Young–Helmholtz theory (based on the work of Thomas Young and Hermann von Helmholtz in the 19th century), also known as the trichromatic theory, is a theory of ...
A color in the RGB color model is described by indicating how much of each of the red, green, and blue is included. The color is expressed as an RGB triplet (r,g,b), each component of which can vary from zero to a defined maximum value. If all the components are at zero the result is black; if all are at maximum, the result is the brightest ...
Stroop effect. Naming the displayed color of a printed word is an easier and quicker task if the word matches the color (top) than if it does not (bottom). In psychology, the Stroop effect is the delay in reaction time between congruent and incongruent stimuli. The effect has been used to create a psychological test (the Stroop test) that is ...
Opponent process. The opponent process is a color theory that states that the human visual system interprets information about color by processing signals from photoreceptor cells in an antagonistic manner. The opponent-process theory suggests that there are three opponent channels, each comprising an opposing color pair: red versus green, blue ...
