Chapter 3

Kowelu's color-blindness is not intended to be a major gameplay restriction.
He supposedly has the sense to label his preps in a way that he could tell
them apart - and having a keen nose also helps. Instead it is an RP device:
his inability to know something that most take for granted creates for him
one more "need" that drives him to seek more and more exotic experiences.

It is likely a neural or mental condition as it's unhelped by shapeshifting.
It also leads to the fact Kowelu has very little fashion sense, his clothing
occasionally displaying a glaring mismatch in colors.
