Interference Colors
The displayed colors simulate birefringence patterns as seen in thin sections under crossed polarizers. Mineral color and opacity are not taken into account.

Michel-Lévy Diagram
The standard representation shows birefringence for a thin-section thickness of 30 µm. The up–down arrow control can be used to vary the thickness and thus simulate a different color scale.

Grain Lattice Simulation
The simulation can be rotated to illustrate how the appearance changes when a thin section is rotated under crossed polarizers.
