I'm seeing 3 violet elements on my screen. "ms" in the top left, the dot next to that text, and a dot on a horizontal timeline at the lower edge of the screen. Scrolling down I see yet more violet UI elements, I assume the one on the vertical timeline represents the data, while all the others represent... other things.
It seems violet is just the accent colour used for everything, which makes it an especially perplexing comment. I can only assume the "author" never even read the LLM's output before posting it.
