By default it blends colors using the LCh color space. LCh is the perceptually uniform equivalent of HSV, and defines colors using intuitive and perceptually-based luminance (perceived brightness), chroma (richness) and hue. If you are doing any kind of image analysis, it's likely that LCh will be much more useful to you than HSV or RGB.
To implement the LCh color space, you first need to implement the Lab color space. Note that the Lab color space provided by this operator is different than the one in Houdini. If you use the Lab color space available in Houdini by default to implement the LCh color space, you won't get correct results.
