12.2.1.2-2 Label Contrast

Lettering and background colors should provide high contrast and high legibility.

Additional Information:
Dark letters on a light background are preferred. Table 11.2 provides examples of color combinations and their relative legibility. Stamped metal tags (brass, stainless steel, and color anodized aluminum) often are illegible under less-than-optimal conditions.
