Are colors really what we believe? You have to know this data
Red, blue, green, yellow, infinity of colors that surround us and amaze us in each object where we see them, we live for them and create incredible things using them as a base, both in art and fashion.
Despite the fact that we see colors everywhere, most colors are not typical of the objects you see, I mean, almost all objects do not produce the colors we see. Let's see why.
Let's briefly summarize how we capture the colors.
The colors, or rather, the waves (the colors come from some kind of light, which is a wave, the only wave of the electromagnetic spectrum that we can see) reach our eyes and are captured by special cells called cones, depending on the wave length, and the cone type, a different color is perceived. There are three types of cones: those that are sensitive to red light, those sensitive to blue light and those sensitive to green light.
Where do the colors come from?
The colors, as we mentioned earlier, come from some kind of light. Here comes the interesting thing is that, unless an object emits its own light with its characteristic color, all other objects only reflect it, and reflect a certain part of that light. You can see in the following image how the LED bulbs emit their own light.
For example, the sunlight is reflected in the leaves of the trees, which we know are green, right? Well, in part. What happens is this, first the light travels and reaches the object (in this case a leaf), as the sunlight is composed of all the colors (white light) those colors reach the leaf, and all the colors of the light except green is absorbed by the leaf, green "bounces" and travels to our eyes, where they are captured by the cones and processed so that the brain perceives the green color.
Colors are a perception of our brain, to make sense of our world, because if you have an object of a color, depending on the amount of light that object will have different shades, changing its color in a certain way, and our brain interprets this as a variation of light. It is believed that our brain evolved in this way to be able to distinguish our food, or to determine if something was in good condition.
Although colors are not strictly necessary to live, they are undoubtedly of great help in our lives, in addition to bringing beauty to our world, even if it is only a perception of our mind. Thank you very much for reading Steemit's friend, and let this community continue to grow and enrich minds.
