![]() Let’s say, my electric bulb is emitting yellow light with its particular frequency and my cones can’t detect this color, but it is kind of close to green and also to red. When we see any color, each color sends its distinctive color signal to our brain. Rods: Used for seeing low-light conditions (It’s of one kind).Ĭones: Comprises of three kinds, each corresponding to red, green, and blue color respectively. We know that light perception happens in a hairline layer of cells called the retina which covers the back of our eye it has two types of light-detecting cells, rods, and cones. Now, let’s see why we see a green color and how we perceive colors. So, we conclude that in this green looking region, the blue and the yellow color are present however, green color is not present in this region. They should coexist like musicians playing bands in harmony. However, you are aware of the fact that light is a wave, and two different frequencies can’t interact with each other at all. These colors don’t rely on human perception.įor example, you might have seen this picture earlier.Īs you can see, the region where the blue and yellow lights overlap is green. We call these colors as physical colors because the color is a physical property of light. In between these two frequencies, we have yellow, green, orange, and blue. High-frequency light means a light with high-energy, so, red light is a high-frequency wave light, whereas violet is a low-frequency wave light. You must have studied that light is a wave and the color of an object is related to the frequency of light waves it emits.
