Small spaces can use dopamine decor effectively by focusing on one statement joyful color to cover about sixty percent of the area, then adding smart accents with thirty and ten percent secondary and accent hues. Incorporate multisensory elements like soft rugs, scented candles, and comfortable cushions to maximize comfort without clutter. Choose personal artifacts strategically to evoke happiness while maintaining open flow. This approach transforms compact areas into mood-enhancing retreats, proving dopamine decor isn’t limited by square footage but by intentional joyful design.
