How does Coloured light affect the appearance of objects?

Objects appear different colours because they absorb some colours (wavelengths) and reflected or transmit other colours. The colours we see are the wavelengths that are reflected or transmitted. White objects appear white because they reflect all colours. Black objects absorb all colours so no light is reflected.

How do objects appear different in Coloured light?

The way coloured light mixes is very different from the way that paint does. When light hits a surface, some of it is absorbed and some of it is reflected. The light that is reflected is the colour of the object in that light.

Why do colors appear different when viewed through different colors of light?

As light passes through the prism, it slows and bends, but different wavelengths bend at different angles. This separates light into different wavelengths, forming a rainbow of colors. The wavelengths of visible light that an object reflects or transmits determine the color that the object appears to the human eye.

Why do certain colors appear different in artificial light and in sunlight?

Artificial light contains very little ultraviolet so the dyes revert to the state in which they do not fluoresce in the visible wavelengths. Sunlight contains significant uv and in sunlight the dyes change to the form that fluoresces at visible wavelengths. That’s why the colour appears only in sunlight.

How do we see different colours?

Light receptors within the eye transmit messages to the brain, which produces the familiar sensations of color. Newton observed that color is not inherent in objects. Rather, the surface of an object reflects some colors and absorbs all the others. We perceive only the reflected colors.

How do objects absorb and reflect colors of light?

When atoms or compounds absorb light of the proper frequency, their electrons are excited to higher energy levels. Colored compounds absorb visible (colored) light and this absorption is responsible for their color. Our eyes perceive a mixture of all of the colors, as in the proportions in sunlight, as white light.
