Theory of color vision based on three receptor types (cones).

Issue where one receptor type can't distinguish between light intensities of different wavelengths.

Vision based on two cone types, allowing perception of limited colors.

Ability to detect heat energy through specialized organs, like snake pits.

Complex color vision due to 16 different types of cones.

Rare cone photoreceptors constituting about 5-10% of cones.

Most common cone photoreceptors, present at 2 per M-Cone.

One photoreceptor type cannot distinguish colors based on wavelength variations.

Photopigment in all rods providing sensitivity to light.

Low light levels where rods are active and color perception is lost.

Different mixtures of wavelengths perceived as identical despite physical differences.

Mixing wavelengths does not change their identity; they remain distinct.

A precise combination of red and green wavelengths required to match yellow.

Mixing lights where the combination of two lights creates a new color perception.

Mixing pigments where some light is absorbed, leaving a different color perception.

Three primary colors are needed to create all visible colors; two are insufficient.

Our visual system operates within the limits of three cone types for color perception.

Scientists who concluded that three primary colors are essential for color vision.

Objects appear a color because they absorb all wavelengths except that color.

Humans have three types of cones that detect different wavelengths: S, M, L.

Neurons that process differences between cone signals rather than individual colors.

Cells detecting light differences between L and M cone inputs.

Small light signals convey position; large signals reveal color composition.

A three-dimensional representation of all possible colors produced by cone outputs.

Describes color using hue, saturation, and brightness.

Ability to differentiate between colors regardless of their names.

Cones work together to interpret a full range of colors and light conditions.

A condition where individuals can see, but cannot process or name colors.

Regions in the visual cortex that respond more to color than orientation.

The idea that perceptions, like color, are influenced by cultural context.

Standardized color names used across cultures to describe colors.

Easier recall of colors when they belong to different categories.

A study showing limited terms (light and dark) still recognize color boundaries.

A genetic condition affecting color perception, more common in males.

The process where color information combines with orientation in our perception.

Private conscious experiences of sensation or perception unique to an individual.

Types include Deuteranope, Protanope, Tritanope based on cone absence.

Individuals, often women, possessing an extra cone type for enhanced color perception.

Inability to recognize objects or colors despite being able to see them.

A condition where a stimulus evokes a sensory experience that typically does not produce it.

Specific colors are associated with letters, numbers, or words in some individuals.

Associating music or sounds with specific colors.

Certain colors evoke vague taste sensations, not specific flavors.
