Color Vision

Color 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.

Photoreceptors and Visual Pathways

Photoreceptors 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,...

Factors Affecting Perception

Factors Affecting Perception

Perception is influenced by perceptual set, context, motivation, and emotion. Perceptual set, or perceptual expectancy, refers to the tendency to perceive things in a particular way, influenced by previous experiences and expectations. This phenomenon affects the interpretation of stimuli, creating a set of mental tendencies and assumptions that impact sensory perceptions of sound, taste, touch, and sight.
An illustrative example of a perceptual set is the scenario where an airline pilot told...

Indicators

Indicators

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...

Area of Science:

Color Science
Display Technology
Visual Perception

Background:

Metamerism, the phenomenon where different spectral power distributions (SPDs) elicit the same color perception, poses challenges in color reproduction across displays.
Understanding display primary characteristics and their impact on perceived color is crucial for accurate color matching.

Purpose of the Study:

To investigate metamerism between different display technologies (OLED and LCD).
To evaluate the influence of display primaries' spectral power distributions (SPDs) and color matching functions (CMFs) on metamerism.
To assess the effectiveness of a color correction model in improving inter-display color matching.

Main Methods:

Conducted a color matching experiment involving OLED and LCD displays.
Analyzed the spectral power distributions (SPDs) of display primaries.
Utilized and compared different color matching functions (CMFs), including CIE 2006 2° CMFs.
Applied a simple color correction model to assess its impact on matching performance.

Main Results:

The CIE 2006 2° CMFs demonstrated better agreement with visual results, particularly for matching between OLED and LCD displays.
The spectral power distributions (SPDs) of the display primaries were identified as a key factor influencing metamerism.
A simple color correction model significantly improved color matching performance between displays, irrespective of the display type.

Conclusions:

The CIE 2006 2° CMFs are more suitable for predicting visual color matching outcomes between modern displays like OLED and LCD.
Display primary spectral characteristics are critical determinants of metamerism.
Color correction models offer a viable solution for enhancing color consistency across diverse display technologies.
