Hi All,

Greetings..!

Would like to understand is there a way to change the color of the text from Grey to Black for all HCM Pages. Attached are two sample screenshots with text having Grey and need to change to Black in all HCM pages. 

change the font color from GREY to BLACK when newsfeed is enabled.  Below snap short Working at home,  FT /PT , Working as Manager, working hours values are displayed in GREY font color.

Similarly for payroll definition page has LDG, As of date, Period type..etc.

Thanks for Help.
