+`colour (string)` Name of the main colour pallete to use. Defaults to `"primary"`, which is a pallete that uses the project's primary colour. If however you are not using `primary` to set a Tailwind primary colour in your project, you can instead set the default colour of the icon by changing what colour classes the primary pallete uses. EG:
+```yaml
+primary:
+    fill:                             'fill-purple-700'
+    stroke:                         'stroke-purple-700'
+    fill-hover:                 'hover:fill-purple-700'

+    fill-group-hover:     'group-hover:fill-purple-700'
+    stroke-group-hover: 'group-hover:stroke-purple-700'

 `hover (string)` Name of the colour pallete to use when the icon is hovered over
 
 ## Reminders
-Remember to add `./config/packages/*.yaml` as a value in your Tailwind config content array if it does not already exist.
