The arousal axis and affect axis are concepts used in color psychology and color theory to describe how colors influence emotions and psychological states.
- Arousal Axis: This axis refers to the level of stimulation or excitement a color elicits. Colors on the arousal axis range from high arousal (intense, vibrant colors like red and yellow) to low arousal (calming, muted colors like blue and green). High arousal colors tend to energize or excite, while low arousal colors are more calming or soothing.
- Affect Axis: This axis relates to the emotional response or mood a color evokes. It ranges from positive affect (colors that are perceived as pleasant or uplifting, such as warm yellows and soft greens) to negative affect (colors that are perceived as unpleasant or disheartening, such as harsh reds or dark grays).
Together, these axes help in understanding how different colors can influence mood, behavior, and emotional state, which can be useful in fields like marketing, interior design, and art.
Here are some examples of colors positioned along the arousal and affect axes:

- Bright Yellow: Energizing and cheerful. Often used to stimulate activity and increase happiness.
- Vivid Red: Intense and exciting. Can stimulate energy and urgency, but might also be overwhelming if overused.
High Arousal, Negative Affect:
- Neon Green: Highly stimulating but can be jarring or uncomfortable for some people.
- Bright Orange: Energetic but can be perceived as aggressive or overwhelming in excess.
Low Arousal, Positive Affect:
- Soft Blue: Calming and serene. Promotes relaxation and tranquility.
- Pastel Green: Gentle and soothing. Often associated with nature and renewal, creating a peaceful environment.
Low Arousal, Negative Affect:
- Gray: Neutral but can be perceived as dull or depressive if used excessively.

These examples show how colors can affect mood and energy levels based on their position on the arousal and affect axes.
