S-view and android 5 - cannot see the name of the caller

[Nikita Honcharenko]

S-view and android 5 - cannot see the name of the caller. When someone is calling and the S-view cover is closed, i see the name of the caller displayed in black font, on the background of caller's photo. It is very hard to see the name.

How to make the black background and white font of caller's name when the s-view cover is closed? As it was on kitkat.
