The unchosen color is replaced with a color on the opposite side of the chosen color. When the same color is chosen twice in a row, this constitutes a reversal, and the step size decreases. After a certain number of reversals, the wavelength/hue of the unique hue is determined.
Attention restoration theory (ART) asserts that people can concentrate better after spending time in nature, or even looking at scenes of nature. Natural environments abound with "soft fascinations" which a person can reflect upon in "effortless attention", such as clouds moving across the sky, leaves rustling in a breeze or water bubbling over rocks in a stream.

In reference to humans, term "red" is often used in the West to describe the indigenous peoples of the Americas.
There is a complex relationship between the wavelengths of light in the visual spectrum and human experiences of color. Although most people are assumed to have the same mapping, the philosopher John Locke recognized that alternatives are possible, and described one such hypothetical case with the "inverted spectrum" thought experiment. For ...
Hue is the name of a color (red, yellow, and blue, etc.). Brightness and chroma refer to the intensity and strength of the color. A high chroma color is more pure and less greyed than a low chroma color. The lightness or darkness to a color is the value. Color also has the ability to work within our emotions. Given that, we can use color to ...
The memory color effect is the phenomenon that the canonical hue of a type of object acquired through experience (e.g. the sky, a leaf, or a strawberry) can directly modulate the appearance of the actual colors of objects.

Research into object-based attention suggests that attention improves the quality of the sensory representation of a selected object, and results in the enhanced processing of that object’s features. [2] The concept of an ‘object’, apropos object-based attention, entails more than a physical thing that can be seen and touched.
