How can I make all objects var/boxcolor that the mob talks to
into usr.boxcolor?

without doing this for every one.
obj/var 
boxcolor = "blue"
mob/var
boxcolor = "red"
obj/person
icon = 'person.dmi'
verb
Talk()
set src in view(1)
boxcolor = usr.boxcolor
Uhh... What do you mean? "objects var/boxcolor" is kinda confusing.
