 - `$font-family` - The global font family to be used by the application.
 - `$type-scale` - The default type scale to be used by the application.
-- `$base-color` - The base text color to be used by the application.
 
 To overwrite the default typography, include the `igx-typography` mixin anywhere after the `igx-core` mixin. Let's take advantage of the type scale `$my-type-scale` we defined above and make it the default type scale.
