Watercolor is a privileged artistic form for elementary school children, since it allows them to have emotional experiences with color in a fluctuating medium like water. At these ages, the way they create on paper is not important. The recreation of a specific character or scene is not important. Working with paint on wet paper, where the water disperses the colors and does not allow them to define any shape, can be frustrating for some children who have prematurely developed reasoning and intellect. Watercolor works from the heart, from the soul, from the emotions, from the flow. The intellect fails when it wishes to define some form. The master's proposal starts from the character of each color: the expansive force of red, the irradiation of yellow, the protective envelope of blue ... and tells a story, presents some images. In these images, characters or animals may appear, each with its own character and activity. So, we identify each character or animal with each of the colors, by the similarity with the character of each color. Finally, we paint the colors on the paper, and we also paint the interactions that each one has had in the story. The result is not a more or less faithful representation of the characters in the story, but a mixture of colors that illustrates the emotional force that has taken place in that narrative.
