Terminal colours are tricky

Terminal color configuration often leads to poor contrast, like the common "blue on black" issue, due to the inconsistent mapping of ANSI colors (16 primary colors) without standard hex values across terminal emulators; tweaking settings via terminal emulator configurations or shell scripts can mitigate these issues, but newer terminals supporting 24-bit colors offer better customization, and features like "minimum contrast" found in terminals like iTerm2 can address the common problem of illegible text by automatically adjusting colors for improved readability.
