This styling Command changes the colour used by the text in the attached hook. You can supply either a string with a CSS-style colour (a colour name or RGB number supported by CSS), or a built-in colour object.
(colour: red + white)[Pink] combines the built-in red and white colours to make pink.
(colour: "#696969")[Gray] uses a CSS-style colour to style the text gray.
This macro only affects the text colour. To change the text background, call upon the (background:) macro.
