Single coatings reflect single colours from the spectrum, e.g. yellow,
green, blue from a lens element. Usually manufacturers choose a
different colour for each element to "cover the spectrum."
Multicoatings reflect multiple colours, not in the spectrum, e.g.
magenta, fuschia, ...
Ideally, get your prism out, shine a bright line & watch the display of
the reflection - or use your spectrometer.
