Artificial lighting significantly impacts how we perceive colors, primarily due to different light sources having varying color temperatures and spectral distributions. Common effects include:
- Fluorescent lights can make colors appear more blue or green-tinted
- Incandescent bulbs create a warm, yellowish cast
- LED lights can vary dramatically in color rendering ability
This is why matching clothes in store lighting might look different at home, or why photographers need specific lighting conditions for accurate color reproduction. The Color Rendering Index (CRI) measures how accurately a light source shows colors compared to natural sunlight. Higher CRI values (90+ out of 100) indicate better color accuracy, which is crucial in settings like art galleries, retail stores, and professional photography.
