Suggestion

Error messages generated by TSC use bright blue and bright yellow to highlight paths and line numbers. These are too close to white to be readable on a black-on-white console.

terminal background color highlight highlighting error unreadable

✅ Viability Checklist

My suggestion meets these guidelines:

• [✅] This wouldn't be a breaking change in existing TypeScript/JavaScript code
• [✅] This wouldn't change the runtime behavior of existing JavaScript code
• [✅] This could be implemented without emitting different JS based on the types of the expressions
• [✅] This isn't a runtime feature (e.g. library functionality, non-ECMAScript syntax with JavaScript output, new syntax sugar for JS, etc.)
• [✅] This feature would agree with the rest of TypeScript's Design Goals.

⭐ Suggestion

Possiblities:

1. Provide an option to just disable color highlighting.
2. (better) Provide an option to switch to a "light background" color scheme
3. (maybe too far) Allow configuration of colors used.

If http://go/gh/microsoft/TypeScript/issues/44233 were implemented, then it would provide a way to do the first option.

📃 Motivating Example

Run tsc on a black-on-white terminal over code that generates error messages.

💻 Use Cases

Primary workarounds:

1. Select the colored text to make it visible.
2. Use a terminal with a dark background and light text.
