Abstract
A system may include: a light valve exposed to incident light from an external light source. The light valve may independently modulate multiple wavelength bands of the incident light that are transmitted through the light valve and into an environment that the system illuminates. A control system can operate the light valve to control a spectral distribution of light transmitted through the light valve.
