Mix test: change color of errors?

Is there a way to change / configure the color “mix test” uses for errors (either runtime or compile time)?

I have this situation where the output is being piped into another terminal, where things are hard to read due to color themes.

Is there a way to change / configure how “mix test” uses which color for errors?

[Link to documentation is fine. “mix test …” is surprisingly hard to google.]

ExUnit.configure/1 supports a :colors option: ExUnit — ExUnit v1.11.3
