Man, I copied and pasted your code and it did not work for me.
see how it was:
It seems that he is not carrying any specific css fabs.
Could you have to do some import?
Thank you!

// Ionic Shared Functions
// --------------------------------------------------
// Makes Ionic Sass functions available to your App
@import "globals.core";
// App Shared Variables
// --------------------------------------------------
// To customize the look and feel of this app, you can override
// the Sass variables found in Ionic's source scss files. Setting
// variables before Ionic's Sass will use these variables rather than
// Ionic's default Sass variable values. App Shared Sass imports belong
// in the app.core.scss file and not this file. Sass variables specific
// to the mode belong in either the app.ios.scss or app.md.scss files.
// App Shared Color Variables
// --------------------------------------------------
// It's highly recommended to change the default colors
// to match your app's branding. Ionic uses a Sass map of
// colors so you can add, rename and remove colors as needed.
// The "primary" color is the only required color in the map.
// Both iOS and MD colors can be further customized if colors
// are different per mode.
$colors: (
primary: #387ef5,
secondary: #32db64,
danger: #f53d3d,
light: #f4f4f4,
dark: #222,
favorite: #69BB7B
);
