=92. Effect of Color Schemes Upon Illumination.= The color of the walls and furnishings makes a difference in the candle power required to give a certain amount of light. Those colors which absorb the most light require the higher candle power, and those reflecting the highest per cent of light require the lower candle power. The frosted globes absorb some light, they diffuse the rest of it. They dispense with the annoyance of glare from lamps, and are useful in places where the full intensity of the lamps is not required. The light absorbed by different colors varies considerably, as shown by the accompanying table: TABLE SHOWING ABSORPTION OF LIGHT PERCENTAGE OF LIGHT COLOR ABSORBED White 30 Chrome yellow 38 Orange 50 Clean pine wood 55 Yellow paper 60 Yellow paint (clean) 60 Light pink paper 64 Dirty pine wood 80 Dirty yellow paint 80 Emerald green paper 82 Dark brown paper 87 Vermilion paper 88 Blue green paper 88 Cobalt green paper 88 Deep chocolate paper 96 =93. Distribution of Light.= Light in rooms for general use should be distributed as evenly as possible thruout the entire room. Avoid excessive contrasts of brightness and darkness. Have the lamps shaded to diffuse the light so that no one need look directly at the filament. When working by a light, do not put the lamp very close to the material, as this produces too strong contrasts of light and dark, or, when reading, it produces too much reflection from the white parts of the paper, which is trying on the eyes. Direct lighting means that the rays from the lamp go directly into the room (Fig. 45). Indirect lighting means that the rays are all directed toward a reflecting surface such as the ceiling (Fig. 46). From here they are reflected, giving an even amount of light to other parts of the room. When directed toward the ceiling, they make it the brightest part of the room. A semi-indirect light avoids this difficulty (Fig. 47). In diffused lighting, the lamp is covered, as by frosting, so that the rays of light are broken up and so scattered that no direct ray shines into the eyes, and there is no bright spot of light in the room. [Illustration: FIG. 46. Indirect light.] When costs must be limited, certain decorative effects must be weighed for their value, some being more expensive than others. City lighting plants can provide current for any number of lamps in a house if it is properly wired. If more lamps are attached than the wiring will carry, and all are turned on, the fuses will burn out. Electric plants for private homes (see Sec. 271) usually furnish current of a different voltage from city electric plants, so special equipment and lamps must be used with small plants.
