I'm assuming you are on Windows 10, You can try to change it here :
Skin studio 10-> Change Skin Colors -> "Edit Colours" Windows -> "Show me the skin Colour presets" click the dropdown button and select -> Show me the skin defined system colours. Scrollbars on the bottom move right -> You will see "Explorer text (Win10)" it is set by default to be black. You can change it to any other color.
