We claim: 1. A bar code reading apparatus comprising: an imaging assembly including a two dimensional solid state image sensor and imaging optics focusing an image onto said solid state image sensor, the bar code reading apparatus having a field of view, the apparatus being configured to capture image data and process such image data for decoding of decodable indicia; an illumination assembly including at least one light source for projecting illumination pattern light toward a target corresponding to said field of view; a user interface enabling a user to select between a first mode of operation wherein the apparatus is optimized for reading black-on-white decodable indicia, and a second mode of operation wherein the apparatus is optimized for reading red-on-white decodable indicia, wherein said apparatus is configured so that when said first mode is selected said illumination pattern light projected by said illumination assembly for reading decodable indicia is narrow band illumination within a first narrow band; and wherein said apparatus is further configured so that when said second mode is selected said illumination pattern light projected by said illumination assembly for reading decodable indicia is light within a second band of wavelengths wider than said first narrow band, and wherein said bar code reading apparatus is configured to decode decodable indicia whether said first mode or said second mode is selected. 2. The bar code reading apparatus of claim 1, wherein said at least one light source is a multiple color light emitting diode having a variable emission band varying in response to one or more signals applied thereto. 3. The bar code reading apparatus of claim 1, wherein said bar code reading apparatus in said second mode projects white light. 4. The bar code reading apparatus of claim 1, wherein said bar code reading apparatus has a display and is configured to display on said display text indicating said first and second modes. 5. The bar code reading apparatus of claim 1, wherein said bar code reading apparatus has a display and is configured to display on said display an indicator indicating said first and second modes. 6. A bar code reading apparatus comprising: an imaging assembly including a two dimensional solid state image sensor and imaging optics focusing an image onto said solid state image sensor, the bar code reading apparatus having a field of view, the apparatus being configured to capture image data and process such image data for decoding of decodable indicia; an illumination assembly including at least one light source for projecting illumination pattern light toward a target corresponding to said field of view; a user interface enabling a user to select between a first mode of operation wherein the apparatus is optimized for reading black-on-white decodable indicia, and a second mode of operation wherein the apparatus is optimized for reading red-on-white decodable indicia, wherein said apparatus is configured so that when said first mode is selected said illumination pattern light projected by said illumination assembly for reading decodable indicia is light of a first color; and wherein said apparatus is further configured so that when said second mode is selected said illumination pattern light projected by said illumination assembly for reading decodable indicia is light of a second color different from said first color and wherein said bar code reading apparatus is configured to decode decodable indicia whether said first mode or said second mode is selected. 7. The bar code reading apparatus of claim 6, wherein said at least one light source is a multiple color light emitting diode having a variable emission band varying in response to one or more signals applied thereto. 8. The bar code reading apparatus of claim 6, wherein said at least one light source is a multiple color light emitting diode having a variable emission band varying in response to one or more signals applied thereto, the light emission from said multiple color emitting light diode changing when said apparatus is switched from said first mode to said second mode. 9. The bar code reading apparatus of claim 6, wherein said bar code reading apparatus in said second mode projects white light. 10. The bar code reading apparatus of claim 6, wherein said bar code reading apparatus has a display and is configured to display on said display text indicating said first and second modes. 11. The bar code reading apparatus of claim 6, wherein said image sensor is a 2D image sensor. 12. The bar code reading apparatus of claim 6, wherein said bar code reading apparatus has a display and is configured to display on said display an indicator indicating said first and second modes. 13. A bar code reading apparatus comprising: an imaging assembly including a two dimensional solid state image sensor and imaging optics focusing an image onto an active surface of said solid state image sensor, the bar code reading apparatus having a two dimensional field of view, the apparatus being configured to capture image data and process such image data for decoding of decodable indicia; an illumination assembly including at least one light source for projecting illumination pattern light toward a target corresponding to said field of view; a user interface enabling a user to select between a first "standard bar code" mode of operation wherein the apparatus is optimized for reading black-on-white decodable bar codes, and a second mode of operation wherein the apparatus is optimized for reading bar codes other than standard black-on-white bar codes, wherein said apparatus is configured so that when said first mode is selected said illumination pattern light projected by said illumination assembly for reading standard bar codes is light of a first color; and wherein said apparatus is further configured so that when said second mode is selected said illumination pattern light projected by said illumination assembly for reading decodable indicia is light of a second color different from said first color and wherein said bar code reading apparatus is configured to decode decodable indicia whether said first mode or said second mode is selected. 14. The bar code reading apparatus of claim 13, further incorporating a display, wherein said apparatus is configured so that a user can select between said first mode and said second mode by selecting a displayed menu option. 15. The bar code reading apparatus of claim 13, wherein said bar code reading apparatus in said first mode projects narrow band light, and wherein said bar code reading apparatus in said second mode projects white light. 16. The bar code reading apparatus of claim 13, wherein said bar code reading apparatus in said first mode projects narrow band light in a first narrow band, and wherein said bar code reading apparatus in said second mode projects narrow band light in a second narrow band different from said first narrow band. 17. The bar code reading apparatus of claim 13, wherein said second mode is a mode in which said apparatus is optimized for reading orange postnet code. 18. The bar code reading apparatus of claim 13, further including a display wherein said second mode is a mode in which said apparatus is optimized for reading red bar codes, and wherein said apparatus is configured to display on said display test indicating a red bar code reading operating mode. 19. The bar code reading apparatus of claim 13, further including a display, the apparatus being configured to display text indicating said first mode, and text indicating said second mode. 20. The bar code reading apparatus of claim 13, further including a display wherein said second mode is a mode in which said apparatus is optimized for reading red bar codes, and wherein said apparatus is configured to display on said display an indicator indicating a red bar code reading operating mode. 21. The bar code reading apparatus of claim 13, further including a display, the apparatus being configured to display an indicator indicating said first mode, and an indicator indicating said second mode.
