uv --color=never shows colors :)

[mattiasb]

If I run uv --color=never --help the help output is still full of colors. :)

This is on uv 0.4.7 FWIW.

I've stumbled upon another manifestation of the issue. Despite the --color=never option is provided, it's ignored when an error is displayed:

For more information, try '←[1m←[36m--help←[0m'.                                                                                

However, NO_COLOR=1 works fine now, in uv 0.4.25 (97eb6ab4a 2024-10-21).

Thanks for catching that @StSav012, I've added a fix for that in the linked PR

In case it helps I think this is another manifestation of the bug
