I got some dirty red tape as follows. I took the bike to my LBS for a repair on a rear hub that was ticking (very tricky problem). After the mechanic had ridden the bike a few times, the beautiful new NOS Cateye red bartape had been suitably "browned" by his dirty hands. I had taken pains to wash my hands and wear gloves while riding this newly built-up bike up until that point, to keep the tape brand spanking bright-red-new *sigh*.
