Question

Hello to my teacher, may he live long. 
What, in your opinion, is reality? After all, the universe is made up of particles and frequencies, but we see structures and colors. So is the way our consciousness perceives the universe the reality, or are we actually in a kind of illusion? Perhaps one could say that until there was an intelligent being to look at reality, it did not exist—not physically, of course, but its existence had no meaning, somewhat like “a poor person is considered as dead.” Therefore, only the way a human being looks at reality is reality. True, a person could also look at reality and invent all kinds of legends for himself, but here it is different, because the perspective here is grounded in material reality. In practice, the existence of colors lies somewhere between matter and spirit, and perhaps one could go even further and say that the existence of other feelings drawn from nature—wonder, for example, at the sun, sunrise, sunset, and so on, even to the point of turning it into a god—are the true perception of the sun. (That does not mean that the sun is a god, etc.; rather, that this feeling of sublimity is real, because that is how a person perceives it.) 
In fact, according to religion, this view has a larger place, since it sees the world similarly through the prism of human feelings. According to Kabbalah, everything here in this world has its source in the upper worlds, and a person is meant to find their connections, and so on.
If I am not mistaken, Kant also speaks about the place where consciousness meets reality. Is that connected to this topic? 
I hope I managed to explain.
