Despite the complex processing that is carried out in human neurons from the moment the light reaches the rods and cones, this was the first human sense to be mathematical modeled through its own space of representation and measurement. Sight gives us information through light, its intensity and color. The world around us is perceived through the senses, and of these, sight is the one which contributes more information to the human brain in its human-environment interface task. The results show acceptable accuracy values that, although obviously do not reach the levels obtained with the other scientific instruments, for the price difference they present a good low cost option. All used scripts (Arduino and Matlab) are attached as supplementary material. Specific software has been developed in Matlab and a study of the linearity of chromatic channels and accuracy of color measurements for this device has been undertaken. The TCS3414CS color sensor (I2C Sensor Color Grove), a system for capturing, processing and color management that allows the colors of any non-self-luminous object using a low-cost hardware based on Arduino, is presented in this paper. This usually requires a thorough knowledge of color spaces, colorimetric transformations and color management systems. The set of mathematical transformations that are needed to transfer a color that we observe in any object that doesn't emit its own light (which is usually called a color-object) so that it can be displayed on a computer screen or printed on paper is not at all trivial. Color measurements have traditionally been linked to expensive and difficult to handle equipment.
