Own Colors Scheme Sporty Pro

If you take own color scheme (apperance/global settings/color options), it makes that in the navigation menu – “the primary color” appears as background as well as text of hover. So, finally the item menu is “empty” when you have hover text.

I used a lot of css styles (simply custom and additional) for formating menu (including formating separately each menu-item). It was hard work, I changed the hover background in all items menu. The problem is the hover text color. I only managed to change the first level menu but I cant change hover text color in the submenu. Nothing happens with the color of hover text in the submenu items. Still the same: “primary color”.

Questions:
1) Why when I use own color scheme, “the primary color” in the navi menu is used the same for background and hover text?? the hover text should be other then background.
2) Why i cant change the color of hover text in submenu for other then “primary color” using ccs styles?
I think you should change sth in the Sporty Pro Theme. The “primary color” overwrite almost everything, also items which not be covered by the “primary color” For exapmple I would like to left the “primary color” as background hover but change the hover text (and not the other way round)
