Discussion
Consider the following statements about the CIELAB white point.
1. Tristimulus values are normalised by those of the white.
2. Different white points give different CIELAB coordinates.
3. The white point has no effect on the resulting values.
Answer: C
The first two are correct and follow from the definition. The third is contradicted directly by the normalisation step in the transformation. White point dependence is built in from the start. Normalisation is the first step of the transform.
