Summary
Researchers demonstrate how to perceive normally unrealizable colors like reddish-green and bluish-yellow. Stabilizing specific retinal image boundaries allows simultaneous perception of two distinct colors within the same visual area.
Area of Science:
- Color perception science
- Visual neuroscience
- Psychophysics
Background:
- Basic color terms (red, yellow, green, blue) can combine to describe other colors.
- Dyadic color names like reddish-green are typically not perceived in reality.
Purpose of the Study:
- To investigate the conditions under which normally unrealizable colors can be perceived.
- To explore the simultaneous perception of two distinct colors in the same visual field.
Main Methods:
- Utilizing stabilized retinal image techniques.
- Focusing on the boundaries between color stripes (red/green, yellow/blue) while stabilizing them.
Main Results:
- Simultaneous perception of red and green was achieved by stabilizing the boundary between red and green stripes.
- Simultaneous perception of yellow and blue was achieved similarly, demonstrating the possibility of perceiving normally unrealizable colors.
Conclusions:
- The study provides a method for inducing the perception of colors that are typically considered impossible.
- Visual perception can be manipulated by controlling the stabilization of retinal image boundaries.

02:39Indicators
Certain organic substances change color in dilute solution when the hydronium ion concentration reaches a particular value. For example, phenolphthalein is a colorless substance in any aqueous solution with a hydronium ion concentration greater than 5.0 × 10−9 M (pH < 8.3). In more basic solutions where the hydronium ion concentration is less than 5.0 × 10−9 M (pH > 8.3), it is red or pink. Substances such as phenolphthalein, which can be used to determine the pH of a solution, are called...

Color in Coordination Complexes
When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human eye.

01:15The Antenna Complex
Plants and other photosynthetic organisms comprise pigments capable of absorption of direct sunlight. These pigments are present in the reaction center - the main site of photochemical reactions as well as in the antenna complex. Under average light conditions, the rate at which reaction center pigments absorb light is far below the electron transport chain's capacity. As a result, the reaction center alone cannot provide enough energy to drive photosynthesis. The photosynthetic efficiency can...
01:14Changes in Skin Color: Clinical Perspectives
The first thing a clinician sees is the skin, so the examination of the skin should be part of any thorough physical examination. Most skin disorders are relatively benign, but a few, including melanomas, can be fatal if untreated. A couple of the more noticeable disorders, albinism and vitiligo, affect the appearance of the skin and its accessory organs.
Albinism
Albinism is a genetic disorder that affects (completely or partially) the coloring of skin, hair, and eyes. The defect is primarily...

01:22Photoreceptors and Visual Pathways
At the molecular level, visual signals trigger transformations in photopigment molecules, resulting in changes in the photoreceptor cell's membrane potential. The photon's energy level is denoted by its wavelength, with each specific wavelength of visible light associated with a distinct color. The spectral range of visible light, classified as electromagnetic radiation, spans from 380 to 720 nm. Electromagnetic radiation wavelengths exceeding 720 nm fall under the infrared category, whereas...
01:24Color Vision
Color perception begins in the retina, the light-sensitive layer at the back of the eye. Two main theories explain how colors are seen: the trichromatic theory and the opponent-process theory. The trichromatic theory, proposed by Thomas Young in 1802 and extended by Hermann von Helmholtz in 1852, suggests that color vision is based on three types of cone receptors in the retina. These cones are sensitive to different but overlapping ranges of wavelengths corresponding to red, blue, and green.
