For ambient lighting, consider how rooms are generally lit. A light source, which can be anything from a candle or light fixture
to the sun shining through a window
, casts its light into the room. The light then interacts with the room's colors and furnishings. Keep in mind that:
- Light-colored surfaces reflect light
- Dark-colored surfaces absorb light
- Matte finishes diffuse light
- Glossy finishes act as mirrors
For visual comfort, especially when working at the computer, uniform lighting is helpful. In terms of brightness, try to get the room illumination close to the screen illumination.
