I'm wondering, why use these expensive color charts for color calibration, when you could get the real thing from a prism.

There are infinitely many more colours than those in the spectrum. Most real colours are mixtures (e.g. browns) and do not occur in the spectrum which consists only of "pure" colours.

The are other colors yes but not many more. The spectrum consists of a near infinite variety of subtly changing colors.

You have already contradicted yourself in just two sentences!
