What colors make up our world

Back to childhood: the sunlight we see when we come to this world from childhood is white, and the colors displayed by each object are various, and at that time I have doubts or curiosities, and I want to explore how this came about. Growing up with this question, when I was reading, I came into contact with the textbook that the light that we can see with the naked eye is composed of seven colors: red, orange, yellow, green, blue, indigo, and purple. Of course, the textbooks at that time would not be so in-depth, because they were too deep to understand, and their cognitive ability would remain at a very superficial level.

However, as we age, we naturally acquire more knowledge and information. After being exposed to the knowledge of nuclear fusion, there is this source of energy that wants to further understand the sun's light. So let's start with how nuclear fusion is generated, as we all know, the earth is not gravity, the objects in the sky are falling down, how people jump have to fall, can't jump to go to space, it's because gravity sucks you down, don't accept it, you don't have the ability to get rid of the earth's gravity, Superman doesn't seem to be able to do it haha. However, the gravitational force of the earth is too small compared to the sun, the mass of the earth is only 1/330000 of the sun, so the gravity generated by the huge mass of the sun is too large, large enough to produce the high temperature and high pressure conditions required for nuclear fusion, and the sunlight produced by nuclear fusion shines on the earth, becoming the source of all things, feeding everything in the world, and giving human light.

When the sunlight hits an object, why there are different colors, this is due to the object absorbing and reflecting the light caused, if you see the object is blue then the object reflects blue light, seeing red is reflecting red light, these are visible light, the wavelength range of visible light is about 380 ~ 760nm; that is, only 380 ~ 760nm of light can stimulate your eyes, so that the eyes produce "vision", and then your brain will react to these visual stimuli, and tell the so-called " Color" is what color it is.

What color is the sky? What color is the snow? What color is hair? ...... The colors make up the colorful world of Over
