Color therapy or chromotherapy is incorporating specific colors into your environment to evoke desired emotional states. It blows my mind how well this works, and that's why you see peach colored walls in offices.

Light works similarly. Warm vs. cool, etc. You can use light exposure to regulate mood, particularly for conditions like seasonal affective disorder (SAD). All of this is culturally-dependent but it works way better than you'd think.

Here are some of the common color associations:

1. Red Emotions: Energy, passion, excitement, strength, urgency, love, anger, aggression.

Therapeutic Use: Stimulates energy, increases heart rate, and can evoke strong emotions. Often used to combat fatigue or lethargy, but excessive use may lead to overstimulation or agitation.

2. Orange Emotions: Enthusiasm, creativity, warmth, optimism, sociability, joy.

Therapeutic Use: Encourages social interaction, boosts creativity, and uplifts mood. Often used to combat depression or feelings of loneliness.

3. Yellow Emotions: Happiness, clarity, intellect, optimism, caution, anxiety (in excess).
