A novel system for coloring the sclera of a human eye, including steps of accessing the sclera, drying a portion of the sclera, applying one or more colorants to the dried portion of the sclera, drying the colorant, and closing access to the sclera. The system avoids tattooing, implanting, and corneal modification. Permanent results may be obtained. Colorants may be coatings or stains.
