The ability to see different wavelengths of light. Light is a spectrum, a continuous sequence or range, of electromagnetic waves, which appear as different colors. Humans and other animals can see some of this range. The part we can see is called the visible spectrum.
ability to distinguish colors and shades; occurs when the color-sensitive cone cells in the retina properly pick up and send normal color signals to the brain
the normal ability to see colors
The ability to distinguish between color, including hue, saturation and brightness.
the ability to perceive differences in color, including hue, saturation and brightness.
This refers to the ability to perceive a difference between two regions of the visual field (two light sources) when the only difference between them is the wavelength of the visible light.
Color vision is the capacity of an organism or machine to distinguish objects based on the wavelengths (or frequencies) of the light they reflect or emit. The nervous system derives color by comparing the responses to light from the several types of cone photoreceptors in the eye. These cone photoreceptors are sensitive to different portions of the visible spectrum.
