Change Sub Menu Hover Colour

Hi, i have been trying to do this myself via the setting but it’s beat me, under the logo area settings, the setting “Logo Area Font Color” sets the colour for the submenu font on hover, but this is the same colour as the mobile menu toggle, so if set to say green, the green text stands out on the white dropdown menu background, but then the mobile toggle menu is green on a green background so you cannot see the 3 lines showing the mobile toggle menu, if i change this colour to white, the mobile toggle menu looks great, with the white lines showing on the green background, but then the dropdown menu does not show the text as it is white text on a white background so my question is:

If i leave the setting as white so the mobile toggle menu displays fine, can you supply some css code to change the colour of the dropdown menu text on hover?
