Text Color Changing?

Some of the text colors on my website are changing from light blue to orange. Any help?

This problem might have been started while trying to installing a new theme.

Please read this tutorial next time you try to install a theme.

I'm not completely ignorant, I know how to change the theme correctly.

Here's my website, look at the most recent posts on this topic. Some random text is orange. And actually look at it, because I don't want some bullshit answer saying that the member can change there text color etc. because that's not it.
