State whether the following is true or false.
A CIELAB lightness above one hundred is possible for a fluorescent sample.

  • A.False only at small scales
  • B.True
  • C.False
  • D.True only at large scales

Answer: B

Such a sample returns more light than the reference white does. The scale is anchored at the white rather than at a physical maximum. Fluorescent samples routinely exceed one hundred. The white is the anchor, not a ceiling.
