Nice! The multiple uses of 
&8&&
are a nice touch. 345 with a few stupid golf tricks: 
@s=(0,(grep$_%3,1..14),15);%m=map{$t=$_,[grep{$z=($t^$_)&7;($t^$_)&8&&
+!($t&8&&~$t&$_&7)&&!(~$t&8&&$t&~$_&7)&&($z<3|$z==4)}@s]}@s;sub t{@c=q
+w(w g c b);join'',map{$_[0]&2**$_?$c[$_]:'_'}0..3}sub p{printf"%s %s\
+n",t(~$_),t$_ for@_;print$/}sub r{my($s,$e,$h,%s)=@_;($s==$e&&p@$h)|r
+($_,$e,[@$h,$_],$_,1,%s)for grep!$s{$_},@{$m{$s}}}r+0,$s[-1],[0],0,1
