How do I separate font/text colours from one another?

[biznazz101]

You can try adding this to the following sections Custom CSS settings (Themes>Customize>Click Section:

Banner CSS:

.banner_heading {color: #FFFFFF;}

.caption-with-letter-spacing {color: #FFFFFF}

Header CSS:

svg {fill: #FFFFFF;}

Before & After:

I hope that helps!
