Lead-containing items on X-ray images are typically shown as which color?

• A. White
• B. Red
• C. Gray
• D. Black or dark blue

Answer: (D)

Dense materials like lead block X-rays strongly, so in a standard X-ray image they show up as very bright areas. That means lead is typically white on conventional grayscale radiographs because the high absorption leaves little exposure for the film or detector. In some color-mapped or negative-style displays used for teaching or specialized viewing, higher density can be represented by darker colors, such as black or dark blue. So depending on the display method, lead might appear black or dark blue in those specific color schemes, but on usual grayscale X-ray images, it would be white.
