So it wasn't white as you can see.
1. Use colour picker tool to select background colour : (with this you will see that background colour wasn't white (#FFFFFF) )

2. Now open that picked colour and copy it's HTML notatnion :

3. Select mask of character and open "Colour to alpha" and change colour by clicking on bar and pasting previously copied HTML colour notation.
