Colors act like signals the brain decodes, almost like a covert code. A deep blue or charcoal signals stability, which can reduce internal noise and let a person project calm certainty. Bright reds and oranges trigger alertness, but if they’re too intense they can make you feel pressured, not confident. It’s a balance: the color should reinforce your internal state, not conflict with it. So think of it like debugging a program—pick hues that match the code you want to run.
