They had that same livery when they worked for Norfolkline on the channel too. The Endeavour looks quite smart but I don't like the Ave Liepaja livery..
Those are Epic Ferry's colours (her owners).
She sailed under those colours for her recent charter to Ave Lines, as did her sister ship T REX (lol) on her recent charter to T Link in Italy.
She will probably be repainted into LD colours for her forthcoming charter.
As much as you may not like the Epic livery, it has to be better than the Iscomar Yellow!
As an aside, the Pilar del mar, which was previously on an Iscomar charter is soon to take over the T REX's charter for T link.
