 % Ajout de la gestion des couleurs
 % The \usepackage is obvious, but the initialization of additional commands like usenames allows you to use names of the default colors, the same 16 base colors as used in HTML. The dvipsnames allows you access to more colors, another 64, and svgnames allows access to about 150 colors. The initialization of "table" allows colors to be added to tables by placing the color command just before the table. https://en.wikibooks.org/wiki/LaTeX/Colors
