How to changing syle of hard coded field?

Hi,
on my forum i have changed theme, and some colors that can be changed from ACP.
But there are styles that i can't change. For example style for text like Location, Age, and so on, that are on shown on forum post (under the avatar).

I checked the code and saw this:
<span style="color:#e2f0ee;">Location</span>

As I see there is no way to change it with CSS... but not to change all span tag.
Any help?
