For airbrush newbies, using cheap dye, like food color, allows an easy and inexpensive way to practice technique. When food color dries one paper, it turns to a color something like dried blood. Each of these exercises use food color in an airbrush (one or more models of Badger or Thayer-Chandler), some with added ingredients, like magenta acrylic paint and/or violet fabric paint, to make the original paintings more permanent. They are then massaged in Adobe PhotoShop (tm) to add color.
