Petite promenade à travers champs disciplinaires dans les domaines colorés par Georges Roque

The conference offers a rich and erudite overview of the multiple disciplinary approaches to color, demonstrating the speaker’s deep knowledge in art history and philosophy. The argumentation is well-structured, progressing from a definition to a systematic exploration of fields, while weaving historical connections and highlighting key conceptual shifts. The scientific rigor is evident in the accurate references to Newton, Helmholtz, and others, and the careful distinction between additive and subtractive color mixing. The speaker also addresses the philosophical debate on the nature of color, presenting both realist and subjectivist positions. The quality of sources is high, as the speaker cites classic works and his own recent book. The title accurately reflects the content, which is a broad, non-exhaustive tour. The main limitation is the lack of depth in each field due to the introductory nature, but this is acknowledged. The talk successfully fulfills its role as an opening to a marathon, setting the stage for more specialized presentations. The speaker’s engaging style and occasional humor make it accessible. Overall, it is a valuable contribution for anyone interested in the interdisciplinary study of color.

The title accurately reflects the content: a broad, multidisciplinary tour of color across various fields.
