When white light passes through a special piece of glass called a prism, the light bends . Shorter wavelengths (violet, blue, and green) bend more than longer wavelengths (yellow, orange, and red). This bending causes the white light to separate into the colors of the rainbow.
How do we see different colours BBC Bitesize?
There are three primary colours in light: red, green and blue . ... 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. For example, a blue object absorbs all the colours of the spectrum except blue: it reflects blue light.
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.

Why do people see different colors?
Inside the human eye, there are two types of cells that respond to light—cones and rods. ... Still, people see the colors of some objects in dim light because their brains have memories of those same objects in bright light . This proves that the colors people see aren’t only determined by wavelengths of light or our cells.

How do you explain colour?
Color is the aspect of things that is caused by differing qualities of light being reflected or emitted by them . To see color, you have to have light. When light shines on an object some colors bounce off the object and others are absorbed by it. Our eyes only see the colors that are bounced off or reflected.
What colour reflects the most light?
The color a person perceives indicates the wavelength of light being reflected. White light contains all the wavelengths of the visible spectrum, so when the color white is being reflected, that means all wavelengths are being reflected and none of them absorbed, making white the most reflective color.
