Light's color is determined by the wavelength of the light energy striking the eye. The eye contains three kinds of cells that are specialized for picking up only certain wavelengths of light. When this information is relayed to the brain, the wavelength is interpreted as color.Know More
The human eye contains cells, called cones, which are filled with one of three kinds of photopigments that selectively absorb only certain wavelengths of light. One is specialized for picking up short wavelengths, another for medium wavelengths and the third for long wavelengths. There is some overlap between the pigments' ranges, but none are able to see the full range of visible light on their own. When one of the pigments is not present or does not work properly, color blindness is the result.
In eyes with normal color vision, light that has a wavelength between 377 and 455 nanometers is perceived as blue, between 632 and 780 nanometers is perceived as red, and between 492 and 577 nanometers is perceived as green.Learn more about Colors
Black absorbs the most light. The color of an object is determined by the wavelengths of visible light it reflects. Black objects do not reflect light, absorbing all wavelengths.Full Answer >
A neon light that is entirely filled with neon gas emits a brilliant red-orange hue. The various colors produced by other neon lights are due to a mixture of other chemical elements, such as argon, helium, krypton, xenon and mercury.Full Answer >
Violet bends or refracts the most as light passes through air and into a prism. This is because violet light in the visible light spectrum has a shorter wavelength of about 400 nanometers when compared to red at 650 nanometers.Full Answer >
Blue is a primary color and cannot be created by mixing other colors. A light blue paint is made by mixing blue with enough white to reach the desired tint. Adding blue to a light green paint will produce a green-blue tint.Full Answer >
