The 60-30-10 color ratio in dopamine decor creates balanced, harmonious rooms that support joy without overwhelming the senses. It assigns sixty percent of your space to a saturated statement color that lifts mood, thirty percent to a secondary, complementary hue, and ten percent to accent colors for contrast. This ratio helps maintain visual interest while avoiding chaos, ensuring the dopamine-boosting colors feel comfortable and inviting. Applying this formula to walls, furniture, and accessories enables you to design spaces that feel vibrant and emotionally supportive.
