A patient has very yellow teeth. A single crown on tooth #12 appears extremely white compared to adjacent teeth. Which dimension of color is the MOST different between the crown and the natural teeth?

Value is the dimension of color that refers to the lightness or darkness of a color (on a scale from white to black). The crown appearing 'super white' compared to very yellow adjacent teeth reflects a dramatic difference in value — the crown has high value (very light/bright) while the natural teeth have lower value (darker/more yellow). Hue refers to the color family (yellow vs. white is technically about value+chroma), but in dental color science, the primary description here is value mismatch.
