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.
Understandable, and "Windows Classic blue" might not be useless if it had a function - let the user filter down to the OSes that shared a given color, so that the reason for it being named such is more clear.
Why do you even need the text? Just show the color, year and the name of the OS.
In many cases, there is some additional information I want to add, like which themes the colors were used as background color in, or which palette they come from if there are several different.
I also discovered a lot about the different OSs while researching the colors and I think it's a nice nod towards the museum character of the site to add fun/nerd facts when I stumble upon them.
But true, in many cases there is no need for text - I just removed the tagline which didn't add anything useful.
