Sela Theme – Issue with Colour Change

I’ve been using the Sela theme for a while now. The colour of the font in my purple main menu bar, used to be white. Now it’s black. I think this may have happened when I ‘accidentally’ hit Save in Customisation. However, there is no option to make the font white again. Do I need to have a premium account to sort this out? I wouldn’t understand if I did need that, because this occurred without me having a premium account.

Hope this makes sense and that someone can help?

Thanks,
Tolu
