<p>Yes, cheerful tones work well in smaller spaces when used strategically. Stick to lighter shades like pastel yellow or light green, which reflect light and make the room feel larger. Avoid using too many bold or contrasting colours in small rooms. You can paint one wall in a bright colour and keep the others neutral. Add little things like cushions or photo frames in cheerful colours to maintain balance. For example, light green walls with beige furniture and yellow accents can create a vibrant yet spacious look.</p>
