Why not the first one? The colors are more interesting, in my opinion.

Here, the green channel has been removed, and the overall palette is closer to HOO. Another version is RGB, where the narrowband data only adds details with minimal impact on the color.

Closer to the HOO second version, right? At least, in HOO, my colors turned out roughly like this.

I typically subtract green from the HOO palette.
