color change not working

when i try to change the icons to white using RGBA or CMYX colors they just dissapear what color code did u use for the colors cause it aint working 

seems changing any color is not working for me any idea?

Hello!
I recommend using the service https://csscolor.ru/hex/ff00008a
You need to select an RGB color, for example white 1, 1, 1, 0.89 and insert it into the desired setting item.
Please skip your example how you write your color code

I still dont understand ur using rgba code rgb is only 3 codes so what do put in for the 4th? 

4 color transparency is inserted.  1 1 1 0.90
