wherein the final beam pattern is emitted in at least a second color range;
wherein the final beam pattern is visibly emitted away from the indirect lighting system without an image of the light emitting element being visible due to the final beam pattern containing no light rays that lead directly back to the light emitting element;
wherein the environment is defined as having a front portion and a rear portion, the front portion and the rear portion being separated by a first plane and the front portion being defined as having a front end through which the final beam pattern travels as the final beam pattern is visibly emitted away from the indirect lighting system;

a support having a surface positioned at an angle configured such that at least a portion of the second beam pattern will impinge into the surface; and
a coating formed on the surface, the coating formed by a first phosphor material and a second phosphor material, the first and second phosphor materials each configured to be excited from the second beam pattern and further configured to emit a third beam pattern after excitation from the second beam pattern, the third beam pattern being emitted in at least two separate colors due to the first phosphor material and the second phosphor material;
wherein the third beam pattern is visibly emitted away from the indirect lighting system without an image of the light emitting element being visible.
8 . The tail lamp of claim 7 , wherein the light emitting element is a blue light emitting diode configured to emit a blue color range and the first phosphor material is configured to emit a red color range when excited.
9 . The tail lamp of claim 7 , further comprising:

10 . The tail lamp of claim 7 , wherein the reflector has a curved geometry such that the reflector surface is curved at a location where the first beam pattern impinges.
11 . The tail lamp of claim 7 , wherein the reflector has a planar geometry such that the reflector surface is flat at a location where the first beam pattern impinges.
12 . The system of claim 7 , wherein the first phosphor material and the second phosphor material are arranged on the surface in a pattern such that the third beam pattern is emitted in the pattern.
13 . The system of claim 12 , wherein the pattern is selected from a group consisting of a logo; a textual depiction; and a signal indicator.
14 . An indirect lighting method for a vehicle tail lamp, the method comprising:
emitting a first beam pattern in a first direction and in a first color range via a light emitting element supported by a substrate, the first beam pattern traveling through a first lens positioned in front of the light emitting element, the first lens configured to focus the first beam pattern;
reflecting the first beam pattern off a reflector surface to form a second beam pattern, wherein the reflector surface is positioned such that at least a portion of the first beam pattern impinges the reflector surface after the first beam pattern travels through the first lens;
exciting a coating on a support surface via the second beam pattern, wherein the coating is formed by a first phosphor material and a second phosphor material on the support surface, the support surface positioned at an angle configured such that at least a portion of the second beam pattern will impinge into the surface; and
