I can't work out how to change colors of text on my pages in Spirit theme

I have a front page modified like in the tutorial and I have a central area with a menu on the right hand side. The letters in the menu are green and go black on hover.
I want to have an overall blue theme and so I have changed all the theme colors to some form of blue and saved it - however the text stays green and I can't find any way of changing that.
Can you please tell me how to change the text color on the menu and also the top menu on hover, or selection shows a greenish background and I want to change that to one of the blue colors of my changed theme colors - how do I do that also (asking this in case the background color change is a different methodology.)
Here is a screenshot to show what the site looks like.
