Is it possible, in practice, to tell the difference between "equivalent" interference colours.
For example say between 1st and 2nd order blue interference colors (~0.012 and 0.025 as an example) - Or is it generally a lot more feasible (as someone who has been dipping their toes in mineralogy/petrology for ~7 months) in practice to use contextual clues in order to difference between them?
