Tagline Color Change?

I have a brushed steel background and the tag line will not show up. I’ve looked all over the place and can’t find a place to change it to something darker. I have changed everything in the "customize section but it has no effect on the “tagline”. Ive gone in and experimented with several of the php files with no effect as well. Thanks for anyones help.

Hi, you can change color with custom css code below (just change color value to desired one):

.header-container h4 {
  color: #fff;

You can apply it with simple custom css plugin.

Thank you. Worked perfect.
