Abstract: A color assurance device houses an array of distinct LEDs lighting sources with each LED array having a distinct color metric index for simulating a distinct light condition to permit color samples to be viewed under multiple simulated colored lighting conditions. Each color lighting condition is at a temperature range that simulates a well-known lighting condition.

Abstract: A sign holder having a bracket releasably securable to a support, an arm extending horizontally from the bracket, and structure releasably securable to a sign. This structure is supported on the arm at least for limited vertical swinging movement relative to the arm in either direction from a median position in which the sign hangs down vertically from the arm. The arm can have at an outer end a universal joint interconnecting the arm and the support structure, this joint permitting rotation of the support structure about an upright axis and providing for a limited vertical swinging movement of a sign in any direction. The arm can also be hollow and have a slot extending lengthwise of an underside of the arm, the slot being of a length less than the length of the arm, the support structure having at least partially circular bearing surfaces bearing on the interior of the underside of the arm beyond opposite ends of the slot, so that the sign can have only limited vertical swinging movement.
