A water color pen is a common drawing tool for children and has various colors. The structural components of the watercolor pen generally comprise: the pen comprises a pen cap, a pen body, a pen tail, a pen point, an ink core and a pen point and pen body connecting frame. After the water color pen is used for drawing on paper, paper works are not easy to store, easy to damage or lose, and inconvenient to share.

In view of the above, the applicant has developed a dot matrix intelligent watercolor brush painting system, which includes dot matrix drawing paper, a dot matrix intelligent watercolor brush and a receiving terminal, and by using the system, pictures drawn on the dot matrix drawing paper can be photographed, decoded and uploaded to the receiving terminal. The system well solves the problems that paper works are not easy to store, easy to damage or lose and inconvenient to share.

However, because the dot matrix intelligent water color pen needs to replace the pen cores with different colors for drawing, different colors need to be identified, and color information is transmitted to the receiving terminal, a method and a system for automatically identifying the colors of the dot matrix water color pen need to be developed so as to meet the requirement for identifying the colors of the dot matrix intelligent water color pen cores.
