Excerpt from Standard Lighting: With Incandescent Electric Lamps Since an Object is seen by the light which comes to it from the source and thence by reflection to the eye, it follows that color in the Object is seen only when the light contains rays Of that color. For example, a red Object will appear black under light in which red rays are lacking or a blue Object will appear black when blue rays are absent in the source. Daylight is composed of all the colors in proportions seen in the rainbow The light from Mazda lamps contains all the colors composing daylight but if the spectra, or rainbows, Of the two were to be compared it would be seen that the Mazda lamp was richer than daylight in the orange - red region and weaker in the blue. For ordinary purposes, the light from clear Mazda lamps is sufficiently like daylight to answer all requirements, but where color discr1m1nat10n is a factor, as in sorting or grading pro cesses for example, and in the laundry where scorch marks must be readily distinguishable, or where the artificial light is used to supplement daylight, as in an Office, daylight lamps, which screen out the majority Of the excess orange-red rays, find wide application.
