Lighting conditions significantly influence colour perception in a room. Natural light enhances the vibrancy of colours, while artificial lighting can alter hues. Warm light sources like incandescent bulbs enhance reds and yellows, creating a cosy atmosphere, while cool lighting such as LEDs can make blues and greens appear more vivid. Different times of day also impact colour perception. To ensure accurate colour representation, consider the room's purpose and select paint home colour schemes under various lighting conditions. Test swatches on walls and observe them throughout the day using a colour shade card to ensure the chosen home colour schemes complement the room's lighting.
