===  Skins and interfaces (Discontinued) ===
Trillian has its own unique skinning engine known as ''SkinXML''. Many skins have been developed for Trillian and they can be downloaded from the official skins gallery or [[deviantArt]].<ref>[http://www.ceruleanstudios.com/skins Trillian's official skins gallery] {{Webarchive|url=https://web.archive.org/web/20081121015351/http://www.ceruleanstudios.com/skins |date=2008-11-21 }} from Cerulean Studio's website</ref>

Trillian also came with an easier skinning language, ''Stixe'', which is essentially a set of [[XML]] Entities that simplifies repetitive codes and allows skinners to share XML and graphics in the form of emoticon packs, sound packs and interfaces.

The default skins of Trillian are designed by Madelena Mak. Trillian Cordillera was used in ''Trillian 0.7x'', while Trillian Whistler has been the default skin for Trillian since Pro 1.0. Small cosmetic changes were noticeable in each major release.

The ''Trillian Astra'' features a brand new design for the front-end UI, named Trillian Cordonata.
