Creating a colour scheme for a room can transform it quickly and cheaply. It is important to consider factors like the amount of natural light a room receives and how colours can affect mood. Warm colours like red and yellow make small, dark rooms feel cozier while cool colours like blue and green are relaxing and make rooms feel more airy. When choosing colours, consider how they may look different in artificial light compared to natural light. Patterns can also be used to make optical illusions and change how a room appears. Texture adds visual interest and different textures like wood or brick feel warmer while shiny surfaces seem more sophisticated. Accessories should be updated to match a new colour scheme for a polished look.
