Textures and colours shape the cosmetic industry. This book highlights the importance of colours and their meaning using Julien Thorn’s beauty photos taken between 2010 and 2020. Associated to images of independent artists, this series of photography allows you to understand the importance of layering and colour associations. They are organised by colour and follow a system of complementary colours to remind you of the colorimetry evoked at the start. This work finishes by raising a question from the 21st century: what place does makeup and colour occupy today? The beauty codes are changing and the Julien Thorn’s photography as well.
