Color Optimisation

hello, here we are with a friend making an addons but here we were told to optimize the colors because there was a better way to optimize, so we changed the colors and created a file with all the colors together, this file in question is generated at the beginning of the server with the loader, but here after checking we are told that the colors are still not optimized and that we must do as its (link give by a moderator) https://www.gmodstore.com/community/threads/PJXuVcbbT9eZWjVSLAVmIw/page/1#post-47927 the problem being that our files make its but for all the colors together.

my question is: is the fact of doing with their technique similar to ours or not?

thank you for your answers
