Abstract	In this paper, an experimental setup composed of a color-mixing device, power supply, and spectrometer is developed. This setup is available for students to do hands-on color mixing with red, green, and blue light in undergraduate labs. LED volt-ampere and spectrum characteristics are investigated. The apparatus was used to perform additive color mixing, and visual colorimetric parameters such as color coordinates, dominant wavelength, and color purity were obtained. This will help students understand the physics of LEDs and chromaticity. In addition, this experiment is useful in introducing topics such as the CIE chromaticity diagram and human perception of colors. (As Provided).
