Feature Icons & Links (Help Please)

Hello!

I cannot figure out why the title on one of my feature icons is not white. Everything else is white, but this one title is stubborn.

Also, I would like to be able to link to my gmail address from my Contact Us page. In the icon box, I am not sure what to put in the link box to make it pull up email and have my email address already filled in. Same thing with calling. When they click call, I would like my phone number to pop up on their dial screen.

The link to my website is http://www.ournewhome-ynr.com

This is what I currently have in the Custom CSS.
.feature-box h4.bold a {
color: white;
}

.feature-box-content {
color: white;
}

.feature-box i.ic-holder-1 {
color: #ffffff !important;
}
.hb-icon-container, .feature-box i.ic-holder-1 {
border-color: #ffffff;
}
.feature-box:hover i.ic-holder-1 {
background-color: #1f1f1f !important;
color: #1f1f1f !important;
border-color: #ffffff !important;
}
.feature-box:hover:not(.standard-icon-box) .hb-small-break {
background-color: #ffffff !important;
}

Thank you for all of your help. It is GREATLY appreciated.
