If I may...

You can change that color only via Custom CSS

.sp-page-title h2, .sp-page-title h3 
{ color: #8dc643; }

(green color from your logo)

I am pretty sure that I shared that idea already in different topic.

You can also add color effects to make Page Title more visible using, for example, text-shadow

.sp-page-title h2 {
  font-size: 70px;
 text-shadow: 1px 2px 3px rgba(0,0,0,0.6);
}

BTW

That is NOT "menu title color" but "Page Title" ;p
