When all participants are in accord on the color scheme, put your energy into aesthetics rather than the problems of conflicting color use. In natural settings the color of light can be useful in establishing the time of day, because the hue of outside light is always affected by the position of the sun. Thus, morning light tends toward orange, while evening light is more pink. The color differences are more effective when combined with changes in position and intensity, but they can nonetheless be a strong tool. The same scene, with variations in light direction and color, can appear to be in the morning, afternoon, or evening.
Light can also be an efficient way to show the passage of time.
A character sitting in the same place all day can be illustrated quickly by a series of shots in which only the lighting is changed. The sequence might begin with the orange light of dawn, followed in the next shot by the hard, white light of noon, and then the pink hues of dusk, finally ending with the blue tint of moonlight. The passage of the entire day is shown with only four shots, and yet the viewer understands implicitly that time has passed and the character has not moved. Our friend the hyena has planted himself at the crest of a hill and stays there throughout the day. The sun is low in the sky, casting long, soft shadows with its orange light.
