COLOR VISION

colour is characterized by 3 qualities except?

• hue

• purity

• saturation

• brightness

What will be the minimum light stimulation where the eyes can start perceiving colours?

• 0.25cd

• 0.50cd

• 0.75cd

• 1.00cd

theory on color vision which suggests that the human eye has three types of color receptors, also known as cones, which are sensitive to different wavelengths of light.

• trichromatic therory of CV

• retinal mosaic theory

• opponent-process theory

• herrings law of equal innervation

On absorption by ocular media how much light is will be absorbed?

• 6%

• 7%

• 8%

• 9%

It is determined by wavelength and gives rise to the characteristic series of sensation when we view the spectrum.

• HUE OR TONE

• BRIGHTNESS

• SATURATION

• PURITY

It refers to the visual perception of how light or luminous a surface or object appears to be

• Hue or tone

• brightness

• saturation

• purity

It is a visual function that allows perception of variation among physical wavelengths of light that compile the visible spectrum.

• visual integrity

• visual efficiency

• visual interpretative processing

• color vision

Theory proposed by Thomas Young and later expanded upon by Hermann von Helmholtz, is a fundamental theory that explains how the human visual system perceives colors.

• opponent - process theory

• wall theory of fusion

• trichromatic theory

• helmholtz theory
