Looks like the rat red haired genes aren't part of the Figarland family, but comes from the mother side
Usually, when Oda draws characters in the B/W manga without inking their hair black/grey and just leaving blank white, it means they're blonde
He has consistently drawn Garling that way even when young, while his two sons have shiny grey hair (which translates to red in colored)
Even the anime does the same (note the darker color difference in Shanks' hair compared to Garling on the left despite both having a reddish light filter)
