I can shade decently, but when it comes to trying to make a background or setting, I find I need to make it fit the environment and looks fake in the basic colors but I don't know how to implement the lighting color and how to choose the color of shadows. I also don't know if I need to change my basic shading colors based on the surroundings or how to do it

You might try these color guides ... just a suggestion.

I am not sure what I am looking for on that page. I'm only seeing some unrelated information unless I'm missing something

Can you post an example picture of what you mean?
