I use this theme at iheartsharing.com. I did change the input background to white color in Edit theme because it's hard to see the blinker when you try to input text. I replace the .gif file in the theme image folder by basic open paint and create bg-.gif(can't remember the exact file name) and replace the bg-.gif. I didn't want to edit the background color but I think it's in the images folder and the CSS. Just look in there. Good Luck.
