    \$\begingroup\$ "vibgyor" can be golfed by 1 byte to .•2Bãθ(•. (Here the explanation for it at the "How to compress strings not part of the dictionary?" section.) In addition, „vr…v r:ð« can be golfed to 'v„v .:. So 28 bytes. Nice answer though, +1 from me. \$\endgroup\$ Commented Aug 14, 2018 at 14:51

    \$\begingroup\$ @KevinCruijssen oh I know all about string compression-- I just figured (as is usually the case with super small strings) that the 3-byte bloat of .•• wouldn't save a byte. Figures the one time I don't actually check is the time it would save bytes xD. Good catch \$\endgroup\$ Commented Aug 14, 2018 at 15:14

    \$\begingroup\$ @Adnan fair enough, the lack of the mirror makes it a significant refactor in my eyes though (that and I doubt I'd've got there on my own :P). \$\endgroup\$ Commented Aug 14, 2018 at 16:47

    \$\begingroup\$ @Adnan also ¬ý is genius... Jeez... You think so differently and it's awesome. \$\endgroup\$ Commented Aug 15, 2018 at 14:53
