My cover was blown, so I asked her to take a walk with me to the Yale Art Gallery to see the Mark Rothko exhibit.

Ideally, knowing, say, what sort of resin Mark Rothko used or which pigments are in a medieval manuscript can help determine the best ways to preserve the objects.

This Mark Rothko-looking blotch of color is the Grand Prismatic Spring, which supposedly gets its colors from bacteria that grow around the water.
