Normally, Angular Material requires a separate .scss file for theming and that file must be included into a mixin where the defined Angular Material themes can be applied. This approach not only forces you to create another .scss file for component theming, but it also forces you to import that file from another place just so you can use the Angular Material mixin to apply the theme.
This brakes the modularity because now you have a reference to your component's theming file from who knows where and you also have to remember to do all this again and again every time you want to use the theme colors from your components.
Fuse, on the other hand, provides a way easier method to add theming to your components: Tailwind utilities!
As mentioned before, Angular Material uses 3 main palettes to generate themes; "Primary", "Accent" and "Warn". Being able to access these palettes and use their colors with your components is a must have feature, otherwise you wouldn't be able to create components, apps or pages that "belong" to your app.
All palette colors are available as Tailwind utility classes, and since these palettes are no more than Tailwind color palettes, they are processed as one by Tailwind, therefore, every single color related utility you have in Tailwind also have primary, accent and warn colors and you can use them just like any other color utility:
There are also other color utilities to quickly set the background or the text color of an element. These special utilities have different values on different schemes. For example, "bg-card" will have different colors depending on the selected scheme so you don't have to set the background color explicitly for "Dark" themes.
