Hi there,

Please see http://themeforest.net/item/the-restaurant/full_screen_preview/111482 there’s a sections on buttons on there, if you add a hex value instead of one of the preset colors in the code you can customise the color of the button.

If you continue to have problems, please let us have a link to the page and the color you’re trying to use and we’ll try and provide the code for you.
