Simply Pink is a theme designed to be used when a more feminine look is needed. The background is a light pink with slightly darker accent images. All text is dark red.
Changing the Font
Several of the headers are graphics built on the fly from a GPL licensed true type font called Penguin Attack. If you would like to change the font you just need to upload your TTF file to the /font/ folder under the theme directory and name the file font.ttf.
Be sure that it's allowed to use the font for commercial purposes. I had a very hard time finding a font that fit the style I was looking for that was free for all uses.
More about the font
There is a script called drawfont.php in the /images/ folder of this theme that handles building the graphic files. It is something I'm working on as a plugin for a future version of ProofBuddy so it is included in this theme more as a test than anything. But this theme just wouldn't look right with boring sans serif fonts.
This theme is available in the Theme Browser or you can download it below.
