Yes i am going to discuss about basic color theory according to physics. I think all of us have very good knowledge about basic color theory. i am just recalling those things in a brief.
In a dark room you will not find out which one is blue & which one is green. So Color depends on light, no light no color.
In the sun light there are 7 color rays , those are Violate, blue, Azure,green, Yellow, Orange & Red. If you wants to find out those rays, you will do another experiment. I will discuss that later.
When sunlight fall on a particle, one ray will reflect and others are absorbed by the paritcle then we will observe that color of the particle. If the particle absorbed all color, we will observe it balck, Alternately if the particle reflect all color, we will observe it white. So every particle have own color characteristic which reflect by the particle and we have seen the particle in that color.
If you want to observe that by an experiment. Take a bule glass and see the red particle. you will observe it as black. Now findout the reason of observing that. A red particle reflect red rays when you observe it by a blue glass, the blue glass absorve red ray then no ray remain for reflect and you will observe it Black.
Thanks for reading the post. If you have any query, you can ask me. Let me keep with you by upvoting and following. Also help me to share another more interesing things to each other.
