Description and determination of an object’s color are not simple. A few standards, such as CIE 1931 and CIE Lab, allow for objective definitions of colors, while several other color spaces are related to special devices, such as printers or screens. Color measurement is normally performed with high-level – and high-cost – equipment to get reliable results.
In a recent project, Agudo et al. have developed a low-cost color measurement system with relatively high reliability, allowing for color detection using an Arduino board and an inexpensive sensor. The software developed in this project is open-source, thus it can even be tailored to fit the needs of the respective user. The results close the gap between color detection by an “educated guess” and the expensive professional devices.
