Use android material default attributes android:textColorPrimary, android:textColorSecondary and android:textColorTertiary instead of defining custom attributes for the same in the app.

Note: Terminology is different between Android default and how we have used them in our app. For eg : Primary text color , which corresponds to android:textColorPrimary in android material theme, applies color to the text in app bar, where as, our primary text color refers to the card titles, important text, etc.

Work on this ticket should fix terminology and make use of android default where possible, instead of defining textColor at xml level.
