. Most people have three kinds of cone cells and every colour stimulates more than one cone. Our colour vision starts with the sensors in the back of the eye that turn light information into electrical signals in the brain neuroscientists call them photoreceptors. Have you ever wondered how we see color.
To see colour you have to have light. Same goes for a banana it is yellow because it reflects the colour yellow. HOW DO WE SEE COLOUR.
This area has millions of light receptors called cones and rods which react to light and tell our brains what colors we see. Some surfaces reflect all of this light while others absorb some of the colours. Thats why when it is very dark we cant see anything.
So when we see the banana the light from the banana hits the cones stimulating them. We see things only when the light that is reflected off of them reaches our eyes. The signals that lead to color vision come from your eyes but it is your brain that makes sense of them allowing you to see a strawberry as red and the sky as blue.
Our Eyes and Light. Our eyes only see the colours that are bounced off or reflectedWe see a certain colour because part of the radiation reflected from the surface of the object reaches our eyes. When light shines on an object some colours bounce off the object and others are absorbed by it.
The retina is covered with millions of light receptive cells called rods and cones. Have you ever taken a bite from a bright red apple and wondered why it looks. Objects appear colored because of the way they reflect light.
Sunlight is a mixture of all colors of light which combine to form brilliant white light. The cones in our eyes are active in light-rich environments and respond most strongly to the colors red green and blue in that order. In addition to the names referenced at the end of this v.
A white ball looks that way because it reflects all of the light that hits it. When these cells detect light they send signals to the brain. How do we see color.

With this logic we know that a tomato is red because it absorbs all colours except red. Our eyes are able to detect how much radiation is entering them and from what direction only if that radiation is within the visible spectrum which is between approximately 380 and 780 nanometers nm. We have a number of.
Seeing colour Toggle text Objects appear coloured because of the way they reflect light. Sunlight is a mixture of all colours of light which combine to form brilliant white light. Light travels into the eye to the retina located on the back of the eye.
