Abstract
Color temperature actually emitted by a light emitting diode (LED) is perceived by a viewer of that LED to be altered because of the placement of a passive color temperature-shifting panel between the viewer and the LED. The panel is colored in a manner to cause a perception of a shift from one color temperature of the light emitting diode to another color temperature of the light emitting diode in the absence of any electrochromic, photochromic, or thermochromic material in the panel.
