Color Vision01:24

Color Vision

942
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.

Photoreceptors and Visual Pathways01:22

Photoreceptors and Visual Pathways

6.8K
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,...

UV–Vis Spectroscopy of Conjugated Systems

7.6K
Organic compounds with conjugated double bonds show strong absorption features in the UV–visible region of the electromagnetic spectrum attributed to π → π* electronic excitations. Generally, a UV–vis absorption spectrum is recorded as a plot of absorbance vs wavelength. The wavelength of maximum absorbance, which manifests as a peak in the absorption spectrum, is denoted as λmax.
One of the factors influencing λmax is the extent...

Changes in Skin Color: Clinical Perspectives

2.7K
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...

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...

Pigmentation01:19

Pigmentation

3.4K
The color of the skin is influenced by a number of pigments, including melanin, carotene, and hemoglobin. Recall that melanin is produced by cells called melanocytes, which are found scattered throughout the stratum basale of the epidermis. The melanin is transferred to the keratinocytes via melanosomes.
Melanin occurs in two primary forms: eumelanin that provides black and brown pigment and pheomelanin that provides red color. Dark-skinned individuals produce more melanin than those with pale...

Area of Science:

  • Linguistics
  • Cognitive Psychology
  • Anthropology

Background:

  • Humans perceive a continuous spectrum of color but use limited basic color terms in language.
  • Cross-linguistic studies reveal significant variation in the number of color terms across languages.
  • Despite variation, lexical color categories show remarkable cross-cultural similarities.

Purpose of the Study:

  • To review the factors contributing to the formation of color lexicons.
  • To understand how color categories influence perception and cognition.
  • To explain the universal regularities and diversity in world color lexicons.

Main Methods:

  • Review of psychological studies on color perception and categorization.
  • Analysis of linguistic data on color terminology across diverse languages.
  • Examination of computational models simulating color category development.

Main Results:

  • Color lexicons are shaped by a combination of human perceptual constraints and societal communication needs.
  • Universal patterns in color categorization emerge across languages, influenced by visual system regularities.
  • Lexical diversity arises from cultural and historical factors, leading to variations in term granularity.

Conclusions:

  • Color categorization is a product of both universal biological factors and diverse cultural influences.
  • The interplay between perception and communication drives the evolution of shared, yet distinct, color lexicons.
  • Understanding color lexicons provides insights into human cognition, perception, and social interaction.
