For each different triplet (R, G, B) we could have a different (and optimal)
matrix A, but this would definitely be something very unpractical. A single

in the following way [205]:
1. Build a set of n test patches of representative or important colors.
2. Under controlled conditions, with a known illuminant (e.g. D65), mea-
