the same paths such as area 406 and 410 each of the functions have been selected to map their values for different input ranges of luminance in this case the below average luminance colors map to more of the input luminance range so the base colors in this case are slightly darker than if the base color function space equator was equidistant between upper and lower apex as is the case in fig4 associating a range of luminance values in which to map a color function space to can involve clipping a color function space stretching the color function space overlaying another space or use of any other mathematical function which can map an input luminance value to an output luminance value 0040 fig6 shows a flow chart of actions that a user undertakes when working with an embodiment of the invention the user selects base color e g step 600 and or injection color e g step 602 functions to apply to a given region the functions can be chosen from a list drawn on a color wheel chosen from a mathematical functions list or via any other method the color wheel may show the allowable hue and saturation values for the mapped value of input luminance for an embodiment of the invention utilizing the hls color system the base and injection color functions are independently associated with a range of input luminance values e g steps 604 and 606 respectively the injection pattern is selected e g at step 608 from a list or by inputting a mathematical formula or by any other means the alpha.
