One of my major concerns when paint the murals was to make the colors seem cohesive over the entire painting. I have the tendency to use color directly from the tube and that can make the images very jarring as one color clashes with another. A trick I picked up in art classes years ago is to use a base color that all other colors of the painting are mixed with. The color from the tubes are then treated as pigments, tinting the base color into various shades. With Madeline's mural I used two colors as a base, a beige and a turquoise. Arianna's mural used mostly a beige and just a little bit of a gray blue.
