Which feature on the $100 bill changes color when tilted?

• A. Raised ink printing
• B. Watermark
• C. Microprinting
• D. Color shifting ink

Answer: (D)

Currency notes use different features to prove authenticity, and the one that changes color when you tilt is color shifting ink. On the $100 bill, the ink used in the front’s numeral 100 shifts color as you angle the bill, typically moving from copper to green. This effect comes from special pigments that reflect different colors depending on the viewing angle, making the note easy to verify at a glance and hard to counterfeit. Raised ink printing is tactile and does not change color with tilt. A watermark appears when you hold the bill up to light, not when you tilt it. Microprinting uses tiny text that’s hard to reproduce but doesn’t change color with angle.
