System and method for color space conversion of color space values which lie outside of a traditional color space boundary

A method of color space conversion comprising the steps of:

• receiving image data comprised of a plurality of pixels having a value encoded in a first multidimensional color space;
• converting each of the plurality of pixels encoded in the first multidimensional color space to a corresponding pixel encoded in a second multidimensional color space, the color space converting further comprising transforming each of the plurality of pixels in accordance with a function of the pixel values in the first multidimensional color space having component values thereof defining a fractional relationship having a numerator portion and a denominator portion, each of which portions include at least one of the component values;
• comparing a value of each denominator portion relative to a threshold value;
• and
• wherein the step of converting further includes converting the plurality of pixels encoded in the first multidimensional color space to the second multidimensional color space with selective substitution of each denominator portion with an alternative quantity in accordance with the comparison.
