Is it possible change a highlighted class variable color?

     As you can see in the screenshot this variable is competely un-readable and I can't find the setting that changes it's bloody hightlight color. The variable is declared as public at the top of the class and this is a class method with the text cursor positioned on the variable. Some help on this would be greatly appreaciated as this has been tainting one of my favorite features of phpstorm with it's gross luke-warm pink!
