Remove tagline in Genesis theme

I'm trying to remove the tagline section from my site. I currently have it set as the same color as my body, and it isn't bad, but it screws up on mobile.

If I take it out in my functions.php, then my body text is covered by my header. It seems like an easy fix, but I have been away from WordPress for too long to figure it out in a reasonable amount of time.
