A Painting Technique Using Ceramic Pigments for the Artificial Iris of an Ocular Prosthesis Guided by Applying Newton's Color Wheel.

This article describes a simple method for painting an artificial iris for the manufacturing of an ocular prosthesis with dark and light tones, both with excellent esthetic results. The challenge of choosing colors around the pupil and medium zone during painting is aided by the application of Newton's color wheel theory. This technique provides a safer choice of color during the painting procedure by using a mixture of ceramic pigments.
