I would disagree with the terminology you use. Today while some liveries (Chinese carriers for example) have outdated liveries, most airlines' liveries would be considered Traditional, Modern or Ultra modern. MX
would be "ultra modern" whereas DL
would be modern and you correctly said QF
would be traditional.
