Discussion
Consider the following statements about cone fundamentals.
1. They represent the cone spectral sensitivities directly.
2. They are related to the matching functions by a linear transform.
3. They are measured by asking observers to name hues.
Answer: B
Correct answer: 1 and 2 only
Statements 1 and 2 are correct: the cone fundamentals are the spectral sensitivities of the three cone types, and they are a linear transformation away from any set of colour matching functions. Statement 3 describes a different kind of experiment entirely - hue naming is a judgement of appearance, not a match, and cannot yield receptor sensitivities.
