Abstract: The identification of colours of objects is a much felt need in textiles, paint industries, cosmetics and so on. The complexity of identifying colour and its matching among several objects has been a requirement for common consumer outlets also. The paper discusses the principles of identifying and matching coloured objects. It uses a multi photo diode array based white balanced sensor from Provotech (India). We have been able to identify among twenty three different colours based on the Chromaticity co-ordinates precisely. The apparatus described is based on a simple embedded controller and the unit has its LCD display to indicate colour, hue and purity so that exact matching of coloured objects can be easily done.Abstract: The identification of colours of objects is a much felt need in textiles, paint industries, cosmetics and so on.
