A method for generating the target color in industrial lighting systems was proposed using the quadratic color model and simplex search method. The target color can be set in a Windows-based system and converted into the XYZ color coordinate system from the sRGB space. A quadratic color model was constructed between the input levels of RGB LEDs and the color coordinates of individual light components in a mixed light source. The quadratic color model is used to cover errors under low luminance condition while using the linear color model. The input levels were determined using the target color and quadratic model. In this study, the simplex search method is applied for determining input levels and is compared with other conventional methods.
