In patients with deeply pigmented skin, color changes may be apparent only in certain areas, such as the:

• A. The nails
• B. The eyelids
• C. The palms
• D. The lips, sclera, or oral mucosa

Answer: (D)

In deeply pigmented skin, color changes are masked across much of the surface, so look to areas with less pigment. The lips, sclera, and oral mucosa are thin and less pigmented, making yellowing from jaundice, blueish cyanosis, or pallor easier to notice even when the skin is very dark. This is why those sites are prioritized for color assessment in dark-skinned patients—the eyes’ whites, inner mouth, and lips can reveal clues that skin color alone cannot. The other areas listed can reflect perfusion or local conditions, but they’re less reliable for detecting systemic color changes in heavily pigmented individuals.
