## What it is
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
