Gallery Widget Navigation Arrows

The Gallery Widget has navigation controls (left arrow, right arrow, etc) that are a light gray color.

Is there any way to either hide them or make them white so that they don’t interfere with the image? It’s OK if they turn black when the mouse hovers on them.

The following Additional CSS was added to change the background and border color of the widget to white.

div#gallery-353-1-slideshow {
background-color: #fff;
border-color: #fff;
}

If more customization is needed, I’d really appreciate it if the entire CSS code (including the above) could be provided. I’m not very good with this.

THANKS!
