Think about your room size, lighting, and decor when selecting purple paint colours for bedroom walls. For smaller rooms, opt for a light purple wall paint to make the space feel more open. In larger rooms, you can experiment with deeper tones, such as dark purple wall paint or regal purple colour, for a dramatic effect. Pay attention to the undertones of purple wall paint colours as well – some shades, like blue purple wall paint, offer a cooler, calming effect, while brown purple paint colour provides a warmer, earthier feel. Testing the colour in different lighting conditions can help you find the perfect shade.
