Yeah, "anyone can paint" is a big theme that Bob harped on a lot through the series run. He talks about it almost every episode, and that's kind of the point of "the joy of painting". It's not a talent show, it's to show you that it's a lot more fun and less difficult than you might think.
Hi there! Looks like you linked to a Lemmy community using a URL instead of its name, which doesn't work well for people on different instances. Try fixing it like this: !artshare@lemmy.world
It’s funny you mentioned yellow, because at the end of this episode he also unveils a nearly identical painting he did with sepia tones instead. He only used white, black, and a burnt umber (deep brown) to mix the sepia tones.
