Hi Laura,
I have not used this template, but it looks like what you need to change is the css found @ this path;
templates > ja_senecio > ja_transmenu > ja-transmenuh.css
The following is the block of code you need to change. The hex for the green color is #92C022 That is what you need to change. You can find plenty of hex color lists by doing a google search.
/* this is the class that is used when the mouse is over an item. script sets the row to this class when required. */
.transMenu .item.hover {
color: #FFFFFF;
background: #92C022;
}
/* this is either the dingbat that indicates there is a submenu, or a spacer gif in it's place. We give it extra margin to create some space between the text and the dingbat */
.transMenu .item img {
margin-left: 10px;
}

.transMenu .item#active {
color: #FFFFFF;
background: #92C022;
/* -moz-opacity: .6;
filter: alpha(opacity=60); */
}
.transMenu .item#active:hover {
color: #FFFFFF;
background: #92C022;
}
Good luck.
