Difficult to define – in general, the visual output resulting from light of varying wavelengths. Short wavelengths = UV Medium wavelengths = visual light long wavelengths = infrared White light is made up of many different wavelengths. When separated by a prism, you can see the colors of the visible spectrum. The color you see on an object is actually the light that is reflected back at you. Black occurs when all colors are absorbed. Color can be described in three different ways: Hue = the dominant wavelength Saturation = the purity of the color Brightness = amount of black in the color In addition to color, itself, the area of the color patch also varies. So in total, we can assess quality according to the three color variables and the area of the patch. Color can be measured using several methods: Comparison to published book colors (Naturalist’s Color Guide) Use of digital camera and computer analysis Use of a spectrophotometer Spectrophotometer works using a diffraction filter that separates wavelengths and guides them into sensors that quantify the intensity.
