New problems appeared with the 4.3 upgrade -- colors that aren't being overwritten by the color schemes section of ultimate branding.
Menu links like MY SITES will flicker with a blue black color before resolving to my branding color scheme. Custom menu links won't even USE the colors set in color schemes. So the result is inconsistent and looks really bad.
Found thru Firebug that the color in question is coming via wp-admin/load-styles.php. Noticing the 4.3.1 version number leads to me to believe they've made some fundamental changes and Ultimate Branding needs to catch up. Hopefully soon!
