Selectable color adjustment for image display

A method comprising:

• directing light along an optical path;
• and
• producing a multi-color composite image formed of a plurality of differently colored composite images by selectively operating in a selected one of a first state and a second state during production of the multi-color composite image;
• wherein in the first state light is directed along an optical path entirely spaced from a first filter wheel and entirely passing through a second filter wheel to produce a multi-color composite image having a first optical characteristic, and in the second state light is directed along an optical path entirely passing through the first filter wheel to produce a multi-color composite image having a second optical characteristic different than the first optical characteristic;
• wherein the second filter wheel is capable of at least one of independent rotation relative to the first filter wheel and rotation about a rotational axis distinct from a rotational axis of the first filter wheel.

A display system comprising:

• means for directing light along an optical path;
• a first color wheel with a given optical filter characteristic;
• and
• a second filter wheel capable of at least one of rotating about a rotational axis distinct from a rotational axis of the first filter wheel or rotating independently of the first filter wheel;
• means for producing a multi-color composite image formed of a plurality of differently colored component images by selectively operating in a first state in which light is directed along an optical path entirely spaced from the first color wheel to produce a multi-color composite image having a first optical characteristic, and in a second state in which light is directed along an optical path entirely passing through the first color wheel to produce a multi-color composite image having a second optical characteristic different than the first optical characteristic, wherein the entirety of the optical path passes through the second filter wheel during production of the plurality of differently colored component images to form the multi-color composite image having the first optical characteristic.
