How do I see colour? (Hands-on Activities) - How is light connected to the colours we see? In this STEAM activity make a colourful light catcher and discover why see different colours?.Can you predict what colour the objects will appear?įor more information on this topic check out these Let's Talk Science resources: Try mixing 2 of the cellophane pieces together.Try using different colours of cellophane.Once the light hits the cones in our retina, it sends a signal to our brain and processes the information we are seeing: yellow! When light reflects off the banana, it hits the retina and depending on the wave lengths of light reflected, it determines what colour we see. Once the light hits the cones in our retina, it sends a signal to our brain and processes the information we are seeing: yellow! Why does it matter? Rods are more sensitive to dim lighting, while cones function best in bright light and allow us to see colour. The retina contains two special types of cells – rods and cones. In the human eye, there is special part called the retina, which is located in the back of the eye. Colour needs light - there is no colour if there is no light. However, if we were to view the red tomato in blue light instead of white it would appear to be a totally different colour.

A red tomato appears red because of materials in its skin that only reflect the red light back into our eyes. We see coloured objects for the same reason. This also works similarly with the green filter and green light. The red filter works by absorbing most of the colours in white light letting only the red light through. In this activity, various filters are used to filter out parts of the spectrum of white light allowing us to see individual colours. White light is composed of all the different colours added together. Light travels in the form of a wave, and each colour has a distinct and different wavelength from another.
