| Abstract: | A method for the construction and calculation of CIE chromaticity coordinates from a simple and inexpensive projection colorimeter is presented. The device allows variation along the dimensions of hue, saturation, and brightness and specification of these variations in terms of chromaticity coordinates, dominant wavelength, relative luminance, and excitation purity. |
