Dispersion Staining

I took a microscopy class last week that was pretty fun.  The class was interesting, but my favorite part was looking at all the amazing colors through the microscope.  I took this picture of some potassium phosphate crystals.  They were white and clear until I added them to a liquid that had a refractive index near the refractive index of the crystals.  The resulting color change is referred to as dispersion staining.  I thought it was beautiful!
