The application I'm using your own mixin to work with color, font and media queries.

Use function in scss "color( name_color , type_color , opacity_color );"

Number 2 and 3 it's optional value, if you don't set them, set will be the normal value and 1 for opacity

background: color(teal, normal,.6);

Include mixin in scss "@include font( name_font , type_font );"

@include font(roboto, regular-italic);

Include mixin in scss "@include media( name_media , type_media ) { @content }"

@include media(phone, general){
  @content
};

You can use your own mixin value, making all similar.

All values are stored in a file builds/development/sass/includes/_stack.scss
