Color can be relative to the other colors nearby. for example, violet can be warm if we see it next to a hot color like red, or cool if we see it next to a colder color like blue.

The answer to this question is "TEMPERATURE". Color temperature can be relative to the other colors nearby of almost in the same location with it such that when a violet that you chose to use is placed beside a hot color like red, it can look like warm but you put and apply violet near the blue color, it looks very cold to your eyes.
