3D Button Color – Customize Color

Hello,

I would love to customize the color of the buttons on this page: http://www.morningstarseniorliving.com/connect-with-us/

I like the 3D option of the buttons here. I know there is a High End 3D button, but the only one that appears to be 3D is the Emerald color. https://hb-themes.com/themes/highend_wp/buttons/#

Is there a way to customize the color? I’ve included a screenshot from the VC for reference. 😀
