Color is a mathematical nightmare
Breaking down the confusing world of color spaces.
The best method that we have for defining color is by using math. Specifically, mind-boggling mathematical models called color spaces that use geometry to assign colors as a fixed point that we can reference, ensuring the blue that I see is the same blue you see. As a creative-leaning person who can barely split a bill without a calculator app, all that math is extremely daunting.
The good news is that computing software will do all these complicated calculations for us...
