A feng shui colour guide is a vocabulary for comparing mood and traditional five-phase associations, not a fixed paint prescription.
Quick answer
Begin with room use, daylight, existing floors and furniture, then test a movable sample before changing a whole room.
Observe colour in the actual light
Paint and fabric shift from morning to evening and under warm or cool lamps. View a large sample beside fixed finishes for several days.
Use five-phase associations as context
Wood is often linked with greens, Fire with reds, Earth with ochres, Metal with whites, and Water with dark tones. These associations vary in application and do not predict outcomes.
Control intensity with proportion
A strong colour may work better as art, upholstery, or a small object than on every wall. Balance visual comfort, cleaning, durability, and the needs of everyone using the room.
Boundary: Feng shui is a cultural and design perspective. It cannot guarantee health, wealth, relationships, safety, or other outcomes. Use qualified professional advice for building, electrical, plumbing, fire-safety, accessibility, horticultural, or medical questions.
