Hey David,
the hover color of the promo text links is determined by the CSS declaration for the top menu hover color (i.e. #nav-primary a:hover). I agree that this needs a separate back-end setting in Theme Options, thanks for spotting this issue!
To change the hover color for the links in question, please add this CSS to the “style.css” file (should open by default when you go to “Appearance -> Editor”:
#nav-primary .promo a:hover { #37B8DD !important; }
Let me know if it works.
Best,
