title: C# WPF ComboBox Mouse over color
body: <p>When the mouse hover over my ComboBox, I get an awful blue/lightblue pair of color for the backgroung of my ComboBox.
  I tried the solutions here :<a href="https://stackoverflow.com/questions/8140067/combobox-mouse-over-color">ComboBox Mouse over color</a>, <a href="https://stackoverflow.com/questions/19913211/wpf-combobox-mouse-over">WPF Combobox Mouse Over</a>, <a href="https://stackoverflow.com/questions/5564104/how-to-style-combobox-background-on-mouse-hover">How to style ComboBox Background on Mouse Hover?</a> or <a href="https://stackoverflow.com/questions/26892005/wpf-combobox-default-hover-color-on-togglebutton">WPF combobox default hover color on togglebutton</a>, but it doesn't change anything, I still get the default colors while hovering.</p>
