What I did instead is to paint the doors on the hall side in the same color (but higher sheen) as the walls on that side, and on the inside of the rooms that the doors were attached to I painted the doors the color of the trim in the room.

Granular Materials. A granular material is a collection of distinct macroscopic particles, such as sand in an hourglass or peanuts in a container. The evolution of the particles follows Newton's equations, with repulsive forces between particles that are non-zero only when there is a contact between particles.onstitutive laws for granular flows. A constitutive relation is an equation that relates the stress in a material to other known variables. The common constitutive relation in fluid dynamics sets the stress proportional to the strain rate.
