When applying the signature to materials to be printed using multiple
colors of ink, the signature can appear in Pantone 202 and white, using
the appropriate Pantone Matching System (PMS) colors, maroon (PMS 202)
gray (PMS 431), black, the darkest color possible, or reversed out of
any color that provides sufficient contrast. A two-color signature of
maroon and a tint of 65 percent black is also acceptable.
