changing menu won't work

Hi guys, I need to change the primary colour of my menu bar. In another thread it says that this should do it: /* For Primary Menu */ #branding #access { background: none #D12429; } However, this isn't working. I changed this to another colour before but I can't remember where I changed it- I am worried I changed some code in one of the theme files. Does anyone have any ideas as to what I may have changed which means the CSS isn't changing the menu colour now? Any ideas would be really appreciated.
