fonts in 2014 theme

I need to change the color in 2014 theme as what supposed to go in sidebar but shows at bottom of page and top are in blue other than the name and I don’t know how to change it.
website is http://www.financialfairy.net
name of site is Show Me the Money.

Can someone please tell me exactly what I need to do to change it and exactly where I have to go to do it? Blue on black does not work!
thanks
