I have a combobox and it's like a simple bar without the arrow. Almost possible to make all sort of color changes except that I can't figure out how to change the default blue color when hovering on the combobox itself. Your help is greatly appreciated. 

What's annoying also is the portion in the styling that seems to be where my answer lies, but even commenting it all out did not cause any issue in building the comboBox, so I wonder if I have to override something to make this happen. It's the portion that is termed "ComboBoxTextBoxTemplate"
