Abstract

A system for accenting an appliqué comprising a lighting system comprising a light source configured to emit polychromatic light, and an appliqué configured to be applied to a surface, the appliqué being configured to at least one of scatter light and reflect light within an appliqué wavelength range. The light source is operable to emit alternating first and second polychromatic lights, the first polychromatic light comprising a maxima within the appliqué wavelength range and the second polychromatic light not comprising a maxima within the appliqué wavelength range.

Claims
