A lighting device may include a housing interior, a light exit, a light source, and a light converter. Output light is outputted from the light exit by emitting primary light from the light source. In response, the light converter emits secondary light of one or more wavelengths different than the primary wavelength, and the output light includes a combination of the primary light and the secondary light. The color of the output light may be tuned by adjusting a color parameter of the output light. The adjustment includes adding a color tuning material at a location in the housing interior where primary light is incident on the color tuning material. The color tuning material is configured for emitting auxiliary light in response to the incident primary light. Subsequently, the lighting device produces color-tuned output light that includes a combination of the primary light, the secondary light and the auxiliary light.
