Changing hover colour and icon colour on accordion menu

I need to customise the colours on the accordion menu. I have used this custom css to change the backgound colour for menu items and active menu items:

#jux_accord-menu .menu_head {
background: #3F3F41;
}
#jux_accord-menu .menu_head.active {
background: #ab9243;
}

However I can't seem to find the code for changing the hover colour for menu items and also the colour of the plus and minus icons (for opening and closing menu items). Can you assist?
