Where to change color of the Title in the Modules

The modules in the Left position are white in color for the Titles. My background is white, so you can't see it. How do I go about changing the color? I don't see it in the template editor.

On the sample page below, there is a Title above the following text, but you can only see it if you highlight it.

"We came here on our honeymoon. We had a great stay in this modern condo, with all the modern accommodations. The beach is about 15 min. and is great for some sun.
- Scott Jackson, USA"

Thank you for your help.

I can not detect what sentence in source and also this is not hot hotel template.

Sorry, please try again. I had changed the template to troubleshoot another issue, and forgot to change it back. It is now set to HOTel template again.

template_css.css:

div.moduletable h3 {
font-size: 24px;
line-height: 24px;
font-weight: 300;
margin: 0;
padding: 0 0 15px 0;
color: white;
text-align: center;
}

remove or change color property
