Change text on invoice of checkout confirmation page?

I'm setting up a store with a black background and white text and it looks great until I get to the checkout confirmation invoice ("main_page=check_out_confirmation" ) which has a white background and white text. How does one change either the background to a dark color (preferably) or the text to a darker color on that one page?

If I can't do either, does anyone have another suggestion?

You can make changes to your includes/templates/YOUR_TEMPLATE/css/stylesheet.css

If you'd like to change the background colour you can change:
**.centerColumn {
background-color: 000000;
}

** or the text to a darker color on that page:
.centerColumn {
color: 000000;
}

It seems like that would change the entire site background, wouldn't it? I only want to change the Order Confirmation offwhite/offgray striped background.

Here's a screenshot of what I'm talking about: http://i1383.photobucket.com/albums/ah287/designer5D/5Dscreenshots/TextIssueQuestion_zpsxitzn9k5.png

I'm not certain what template you're using? Can you send the link to your site? (with a dot com perhaps)

Problem has been fixed. Here was the solution:

in includes/templates/template_name/css/stylesheet.css lines 643 and 647 which are .rowEven and .rowOdd respectively. Change the background-color to #000000

Glad you fixed it!
