The Colour and Colour Naming conference, held in 2015 at the University of Lisbon, offered a chance to explore colour naming processes from a cross-linguistic approach. The conference was an initiative of the working group Lexicography And Lexicology from a Pan-European Perspective, itself part of the COST action European Network of Lexicography. The working group investigates the various ways by which vocabularies of European languages can be represented in dictionaries and how existing information from single language dictionaries can be displayed and interlinked to better communicate their common European heritage. The proceedings gather together a selection of studies originally presented at the conference. The first section of the volume outlines a Pan-European perspective of colour names; the second section is devoted to the categorisation and lexicographic description of colour terms.
