# Important note

These styles added because there's an issue with contrast value of the text in mdc based buttons and some other components in Angular Material.

According to [bug(button): Palette contrast values are not applied #26056
](https://github.com/angular/components/issues/26056#issuecomment-1823079154) (Also these issues: [27192](https://github.com/angular/components/pull/27192) and [26179](https://github.com/angular/components/issues/26179)), Check out this [repo](https://github.com/Plabbee/angular-material-contrast-fix) for more information about fixing this bug.

When the bug fixed by Angular team it's better to remove these styles.
