Customising themes: How to change the menu font colour?

Hi!
I’m making my custom gtk theme by using gtk-theme-configurator. This tool can change background and text colors of gtk themes. But it doesn’t change the Mate menu text color, which has “Applications, Places, System” menus. Also, the clock app color is unchanged too. For me it changes the Window bars’ text colour, and background color changes work too with the app.

My quetions is how to manually change those font colors. I tried to edit the css file of the theme, but I couldn’t generate any change with menu and time apps.
