COSCO (HK)’s blue flag has combined white CHS letters with a slight lean. Kang Hong and Kang Yu provide differing blue funnel renderings; NJK favours C937’s shade over C938. Hong Hing photographs also vary, possibly through camera or image adjustment. The CHS scheme appears chiefly on ships with Chinese or CHS-prefixed names, without a definitive rule.
Yick Zao and Yick Luk used Tong Ling’s red funnel with white T, subsequently dropping T to leave plain red. Rosanoski explicitly corrected his earlier attribution of this design to Yick Fung. Yick Zao retained the plain-red version until sale in 2010.
Ocean Tramping’s plain yellow or buff funnel persisted on Mass- and Joyous-named ships, including Mass Glory and Joyous Land. Photographs vary between yellow and buff.
