One thing that isn't a rule but I use

And when I make a paint, is that I use mix with all the colors, any color that is composed by the red but the orange without other combination with red, or I gonna have a paint that remember the arid there even have green, like cactus, and I never like that paint with that ressemblece, and the green need be treated, arid cactus have a very strong green, tropical leaves have a very strong green, and the sky at end of the day could be very orange remembering that the death is something that always happens nobody need live in that state, so maybe the person is making a image that valorize all that, even the blue, have to be well thought have during the year the bluesky with diferent tons, a little hot blue maybe remember energy, maybe is that you need passes energy to people to they don't relax when they need work or need be proactive so the blue have many meanings, if you don't need someone relax till want went bed maybe the blue have to be more warm, when you see a paint, the colors on it, have the abstract art, is very important to see how he used the colors to see if the person is an good artist, when I use the red I am using a strong color maybe I am telling a history of the red, I think the red is disruptive.
