+# Bash colors.
+
+## How to use.
+Most of the time you want to use it with `echo`. To make `echo` respect colors, you need to use `-e` flag like that:
+```bash
+export color_default="\033[0m"
+export color_red="\033[0;31m"
+echo -e "${color_red}hello world!${color_default}" # will print "hello world!" in red.
+```
+
+## List of colors.
+Please note that colors depend on Terminal Emulator and may vary based on its settings.
+
