Changing color of buttons

Hello, I would like to know how I can change the color of buttons to my corporate red color. I have choosen the "brick" color but would like it to be red. Can you point out what file this is in? You have guided me before in changing colors in files using photoshop, so I would guess this would also be an easy change. Thanks for the great support as always.

regards
Scott

You should edit image files in Photoshop and upload (overwrite old).

yes, that's what I thought... do you happen to know the name of this file for the brick red?

"modules/mod_hot_image_slider/images/slide-nav-brick.png"

I'd like to recommend you Firebug extension for Firefox browser. Install it, click on the bug icon (lower right corner), mouse over the element on screen and you will get all information you need.
