Abstract :
The CIE color matching functions, which are the foundation of computational color, are constructed and tabulated from experimental data by using various interpolations and smoothing. This work shows how the exact form of the mathematical operations used to construct the tabulated values can produce a bias in the computation of tristimulus values when used with sampled data obtained from various measuring instruments. The practical limitations caused by the bias are discussed
