You will get more value out of a more specific question or context.
Consider posting some art and get thoughts on the colors.
We could talk about this in a lot of ways.
But 3 important things to think about:
Subject Matter --> what it is
Feeling --> how it is presented
Viewers --> how should people feel about what it is when it is presented to them
Use colors to serve the image, your intentions, and ensure people digest it the way you want them to.
I want a realistic palette, but how should I do it?
Study light.
The real world renders the way it does because of how light interacts with objects of various materials.
It's just like one or two colors with a lot of tones.
Using hues and tones is useful for fast iconic color picks.
But you should explore color mixing to open up a new dimension of choices.
