So, GDB 16.2 (from unstable) supports NO_COLOR (https://no-color.org/), so that should be an easy way to disable colours on it. GDB from bookworm and unstable both support "set style enabled off", which does what you want. I understand that the request here is that GDB should be aware of TERM and set things accordingly, but I don't consider that to be an important bug, so I'm adjusting the severity to wishlist. Meanwhile, if that's still something important for you, could you: 1) Verify that GDB from unstable/bookworm still suffers from this problem. 2) File an upstream issue if that's still the case.
