Some texts are unreadable because of inappropriate contrast color choice.

I can't remember all cases I noticed it, but I took a screenshot on the Wallpaper settings window, where as you can see, texts in the choice list are unreadable.

I tried with many dark themes (not only Dark Breeze) : Ardour 4, Obsidian Coast, Breeze High Contrast, Papirus Dark, Zion (Reversed).
All dark colors themes have this problem with text.

Reproducible: Always

Steps to Reproduce:
1. Choose a dark theme in the "color" settings (apparence), and Apply
2. Right click on the desktop and select Desktop Settings
3. Open a choice list, and notice the contrast text problem

Actual Results:  
Text are white on a white background

Expected Results:  
A contrasted color should be choosen (in my case Wallpaper setting, I think that the background should be dark, and the text should be white).

It is a big problem, as it makes some essential settings of Plasma unreadable. The global feel is destroyed with such bugs. That's why I selected "Major" Severity bug.

Some of us, are really uncomfortable with white themes. So Dark themes are essentials.
