Seconded. The "personality" it tries to add is trite and tiresome and everybody immediately sees it for what it is, especially for a case like this where there's only so many ways to say "this is the default desktop color of an operating system." Not only that, but it's confusing - is "Windows Classic blue" a real thing, or just an attempt at a cute phrase? Just label the colors and be done with it.
It's actually not so easy to pick a speaking name for each color, since many colors are used in different OSs. I tried to use neutral and standard color names were they exist. Things like Windows Classic blue are probably always description-slop, though.
Another user suggested to use media quotes etc. on OSs, which I think is actually a pretty good idea. I might swap the LLM generated placeholders for something like that.
