colout is a Python command-line tool that colors text streams piped through it, highlighting characters matching a regular expression in a chosen color and style. It supports 8/256-color modes, colormaps, themes, and Pygments-based syntax coloring while preserving surrounding context.

Use cases

• colorize command output in the terminal
• highlight errors in log files
• add colors to grep or tail output
• color specific parts of ps or ls output with regex groups
• syntax-highlight source code snippets in the terminal
• apply rainbow colormaps to long log lines

When to choose

• you want grep --color-like highlighting that keeps the full context
• you need flexible regex-based coloring with multiple colors per line
• you want a simple pipe-friendly tool for terminal output styling

When to avoid

• you need persistent file editing or syntax highlighting in an editor
• you want structured log parsing rather than visual coloring
• you need Windows-native console support without ANSI escape support
