an orange or brownish tint. At sunrise and sunset, the color can be more
orange or red than yellow.
Shadows are more distinct the clearer the day is, and can be essential for

A directional light can also simulate moonlight, which is white but dim

Artificial Light
A scene illuminated by point lights, spotlights, or distant lights is artificially
illuminated. Therefore, it can be helpful to know how light behaves.
When light rays strike a surface, the surface reflects them, or at least some of
them, enabling us to see the surface. The appearance of a surface depends on
the light that strikes it combined with the properties of the surface material,
such as color, smoothness, and opacity.
Other factors, such as a light’s color, intensity, attenuation, and angle of
incidence also play a role in how objects in a scene appear.
