### Bug description:
I noticed that the magenta color used by the new REPL and within the non-error text in the new colorized tracebacks in 3.13 looks quite a bit like an error-related color in some popular color schemes.
Here's an image which shows how an error message displays in a few fairly popular terminal color schemes.
![magenta](https://github.com/python/cpython/assets/285352/9367b293-55c5-4621-9af9-9812f50e5282)
I've included both "bold as bright" and not.
Some terminal emulators enable that setting by default while others do not.
Here are 3 more images showing how the prompt and error messages would display if cyan, blue, or green were used instead of magenta.
![cyan](https://github.com/python/cpython/assets/285352/d8dae7ed-4a84-429a-9579-a01f53b7566b)
![blue](https://github.com/python/cpython/assets/285352/c42b037b-b225-4a73-840c-f413bf4a0c06)
![green](https://github.com/python/cpython/assets/285352/10bd2730-7c55-4a67-aa8f-1b147069e6d9)
[A script I used to help generate those images](https://pym.dev/p/2f8ks/)
I couldn't find data on which color schemes are the most widely used, so I took my best guesses from a bit of research.
>From the schemes I looked at (Dracula, Nord, Solarized Dark/Light, Gruvbox Dark/Light) I think Cyan, Blue, or Green would look the least like red.
I don't want to start a debate over what color to paint the bike shed, but I think the closeness of the magenta and red colors are important enough to discuss before 3.13.0 lands.
