Surface color is one of the most appealing factors that influence the consumer in the purchase of fruit. To this extent large research efforts are devoted to the development of new cultivars that improve color attributes of fruits. At the present stage, for the precise quality assessment process the colorimeter only is available to provide standard color measures.

However, this instrument provides just punctual information on the surface color of the fruit. The aim of this research is to develop a system able to grade fruits on the base of the whole surface of the tested sample, and so independent of the bias introduced by operator the choosing the measurement points on the fruit surface. In this way, the researchers and the operators could have at their disposal a new measurement system to grade the quality of the fruits.
