// Named Color Variables
// --------------------------------------------------
// Named colors makes it easy to reuse colors on various components.
// 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.
$colors: (
primary: #387ef5,
danger: #f53d3d,
light: #f4f4f4,
favorite: #69bb7b,
gray: #898989,
stranger : #5dc3b5,
