Step 1 Paint Test Panels to Find the Right Colour
Before finalizing your wall colour choice, paint test panels with the colours you are considering. Purchase blank test panels from a paint centre or make them from cut-up drywall, hardboard, or foamcore board. Compare candidate colours under all the lighting conditions you will find in the room over the course of a full day and evening. Remove all of the electrical cover plates on the wall. Reinstall the screws in the outlet box to avoid misplacing them. Pull off dimmer knobs, cover the switches and receptacles with masking tape.
