Honestly? I've been painting since enamel was the default, and I gotta say: nearly everyone who's trying to sell you paint pots is simply repackaging tube paints. With the advent of the internet, there is a wealth of both text and video tutorials on simple color theory training, to the point that a single weekend of goofing off and making mistakes can train you to a commanding point of expertise in not only saving money by buying acrylic tubes of paint, but also avoiding the other BS of "speed paints" (eg. OG mixes of acrylic + flow medium + veg glycerin; look it up) and "texture" putties, etc. (literally dirt + paint, FFS).
Feel free to DM if you want links, etc. This hobby is about agency and education, not paying corpos their fucking troll toll. ๐ค๐ผ
