Do you mean default here?  That is, it is possible that A might not have
yellow skin colour.  If so, then there are LOTS of problems.  (Think of
people who are multi-racial.)  If not, then you are not talking about
defaults, but instead known values or fillers.  There are lots of solutions
to fillers that clearly make the distinction between properties of
individuals and properties of classes.
