Fortunately, I can make this decision retroactively for photos shot

Probably somewhere in between the two roughly speaking the colour of
freshly cleaved basalt for the darkest of the light bits.

If you really wind up the colour contrast/saturation in HSL space you
can actually see very slight differences in lunar geology.
