This work was an investigation for a thesis project in the Electronic Engineering Faculty, at the Ricardo Plama University. It was then that the idea of ​​physically implementing a prototype of autonomous painting supervision and control was born, making use of an artificial intelligence algorithm mainly the fuzzy logic algorithm. For this, it was established the use of two input linguistic variables and one output variable. Also, for the image capture stage, a Webcam camera was used. In addition, a PC was used where the Fuzzy Controller was algorithmically programmed using LabVIEW graphic computing software. Thus, as part of the processing, the image captured in the RGB color model was converted to the CYMK color model, and for this the Fuzzy Logic algorithm determined the amount of color required except in the case that an error had occurred, either due to lack of color or the excess of this, the second linguistic input variable of the fuzzy controller had to be used. The results obtained in this work were that image capture, always involved the problem of lighting, as well as the characteristics of the inks, which caused the final results to vary. In addition, although the algorithm of Fuzzy Logic became a very versatile tool, and easy to modify it in case it had been required to change its use or application, even so, the results are not very precise. The final stage was made by controlling solenoid valves in isolation, in a time of opening and closing in gave way to the release of each painting corresponding to the colors Black, Cyan, Magenta, Yellow and White or Luminance. The latter was considered as additional by the brightness that exists in the captured image
