Change Color on Form Submit Button

Currently, the color of the Submit buttons on the forms is blue. I'd like it to match our brand colors. Would it be possible to change it to Hex #988377?
Thanks

All of your leadbox submit button have been changed in color by adding this code to the bottom of your stylesheet:

.leadbox-submit {
background-color: #988377;
border-color: #988377;
color: #ffffff;
}

The stylesheet is accessed from the main menu: "Settings" -> "Administrator" then click on "Stylesheet" from the list.

Thanks Dave!! You are the best!
