With standard pixel color filtration (pictured), one is able to quickly fill the pixel well. However, that value is much less accurate as it contains unwanted and impure color information.
With a better color filter array, shown in the example, the Trichromatic is able to use the full potential of the pixel well to capture only the pure and wanted color data. This provides for maximum color saturation values to be captured at a sensor level while still maintaining complete luminance detail.
The Trichromatic color filter array is a more efficient utilization of the electron wells in each individual pixel. As the pixel no longer has to compromise by capturing impure color information, we are able to further tune the sensor to its maximum efficiency and achieve a lower base ISO setting (ISO 35).

Traditional sensor manufacturers might view having less color filtration as a way to improve sensor sensitivity and thus achieve higher ISO performance. However, this is somewhat of a paradox as most of the extra sensitivity gained ends up being reduced again in color processing, leaving only the drawbacks of that compromise.

Purple fringing is described as an out-of-focus magenta “ghost” that can appear as a coloring and lightening of dark edges next to areas of bright illumination, resulting in a purple anomaly and a loss of edge contrast. This is caused by a combination of many factors in digital photography, both from the optics and sensor. Precision optics, optical UV coatings, and software algorithms can mitigate purple fringing, but its effects in compromised edge contrast will always be a factor unless addressed at a sensor level. The Trichromatic has a significantly higher resistance to purple fringing owing to cleaner color separation.
