Work hard, think hard

I have been thinking about interference,

"If a crystal illuminated by white light is viewed with the crossed polarizers off the extinction position, colors, known as interference colors will be seen.  These colors result from unequal transmission by the analyzer of the various components of white light.  What wavelengths are seen depends on the retardation or path difference produced in the crystal for each of the wavelengths."


I still don't get it..
