Hi
Its style code

.t4-palette-dark:before {
    background: #fff;
    content: "";
    position: absolute;
    left: 50%;
    top: 0;
    margin-top: -22.5px;
    margin-left: -22.5px;
    height: 45px;
    -ms-transform: rotate(-45deg);
    transform: rotate(
-45deg
);
    -webkit-transform: rotate(
-45deg
);
    width: 45px;
}

The middle arrow is from this code

.t4-palette-dark:after {
    background-image:url();
    background-repeat: no-repeat;
    background-position: center;
    content: "";
    position: absolute;
    left: 50%;
    top: 6px;
    margin-top: -22.5px;
    margin-left: -22.5px;
    height: 45px;
    width: 45px;
}

In background u can change the arrow down image to your image path.
