I noted earlier that the color of light is an important part of our perception of light quality. The color of light is measured on the Kelvin scale as temperature. Perceptually warmer colors (those toward the red end of the spectrum) have a lower color temperature than perceptually cooler colors (those colors that are bluer) which have a higher color temperature. For more on the color of light, see pages 34–39. It’s important for photographers to be able to differentiate between different colors on the spectrum, because the rendition of color has a huge impact on the final appearance of a photo. The color in your photo will primarily be rendered according to the color temperature of the lighting and the white balance settings applied to that lighting. Most digital cameras have a built-in color spectrometer, which is what sets the color temperature when you leave White Balance on Auto. If you think you know better than your camera (which can often be the case) you can set the White Balance, either to a Preset such as Daylight or to a specific Kelvin temperature.
