The dopamine decor trend in 2025 focuses on decorating spaces to boost happiness by using color psychology and neuroscience. It combines saturated colors like chartreuse, coral, and lavender with personal memories and multisensory elements to activate the brain’s reward center. This design approach prioritizes joy and emotional connection over rigid rules, making your home feel as good as it looks. To start, perform a joy audit of your favorite colors and textures, then layer them thoughtfully to create a space that continuously uplifts your mood.
