I see.
Well I suspect that may be neither the result of your theme’s stylesheets nor those of our plugin. Did you copy and paste that text from another source such as a word processor document, email or another website?
It has a number of inline style rules (which take precedence over those in stylesheets) and one of those is setting the text color to black.
If you are unsure what I am talking about then the best advice I can offer is to edit the text again (switch from HTML to plain text mode) and wipe what is there – replacing it with a “plain text” version.
Does that help?
