To create these magic trees we paint a chromatic shade with tempera colors on a drawing sheet. First we start the shade with yellow: we add a little amount of red into the yellow paint and proceed painting the orange tint until we reach the pure red. After that we add a little amount of blue into the red paint and proceed painting the purple tint. In order to obtain this chromatic shade we need to work quickly, because the painting on the sheet has to be wet for being shaded. Take care to mix the color on the palette and on the sheet before it becomes dry.
After creating the chromatic shade, the students have drawn the silhouette of a tree on the colored background, inspired by the shape of oaks. We colored the negative space of the image with black paint in order to emphasize the shaded colors of the tree. At the end the silhouette of the tree has been decorated with free zentangle, making these trees even more magic.
