- Light is made up of different wavelengths, or colors, and white light is a combination of all of them. When a ray of white sunlight hits a patch of beach ball, the paint absorbs most of the wavelengths. It reflects the rest. For example, if the patch is blue, it reflects the blue wavelengths and absorbs all the others.

Aug 11, 2023 · For example, if an object appears blue, it’s because it absorbed all the other color waves but reflected the blue waves of white light. If the object is a mixture of colors, it reflects those colors while absorbing the remaining color(s).
Our eyes only detect three colours: red, green and blue. By combining these, however, we can perceive many different colours. By mixing red light and green light, for example, we can see yellow.
Jul 23, 2019 · That means there are also three types of colour blindness. The type depends on which type of cone that is missing or not working. The loss of red cones is called protanopia. The loss of green cones is called deuteranopia. We usually refer to both of these conditions as “red-green” colour blindness.
This mix of colors and white light is what lets us see colored objects. When sunlight hits a beach ball, we see only the light that bounces off of it. Different parts of the ball reflect different colors. The yellow side reflects yellow light. The blue side reflects blue light.

Visible light is the small part within the electromagnetic spectrum2that human eyes are sensitive to and can detect. Visible light waves consist of different wavelengths. The colour of visible light depends on its wavelength. These wavelengths range from 700 nm at the red end of the spectrum to 400 nm at the violet end. White light is actually made...
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. For example, a red shirt looks red because the dye molecules5in the fabric have absorbed the wavelengths of light from the violet/blue end of the spectrum....
The retina6of our eyes contains two types of photoreceptors – rods and cones. The cones detect colour. The rods only let us see things in black, white and grey. Our cones only work when the light is bright enough, but not when light is very dim. This is why things look grey and we cannot see colours at night when the light is dim. There are three t...
The primary colours of light7are red, green and blue. Mixing these colours in different proportions can make all the colours of the light we see. This is how TV and computer screens work. If you look at a screen with a magnifying glass you will be able to see that only these three colours are being used. For example, red and green lights are used t...
Aug 8, 2011 · Scientist Beau Lotto examines why we all see colour differently, using our brains, not our eyes.
Oct 11, 2024 · Blue light is scattered in all directions by the tiny molecules of air in Earth's atmosphere. Blue is scattered more than other colors because it travels as shorter, smaller waves. This is why we see a blue sky most of the time. Closer to the horizon, the sky fades to a lighter blue or white.
