# Colorful Output

If you have skimmed through the reference, you may have noticed that the command say is sometimes used instead of Ruby's puts. This is provided by the Colsole gem, which is bundled with Runfile, and available inside your actions.

In addition, Runfile itself, prints most of its output using say, which means you can use Colsole's color markers in some other places

Colsole's primary function is to provide a way to easily print colorful strings.

say 'r`This will be in green`'
say 'nb`This will be in normal bold`'
say 'rubi`This will be in red, underlined, bold, inverted`'
