Yosemite Lite Site Title won’t change color in live version

Hi there!

I’m using Yosemite Lite and I’m able to change the site title in appearance -> customize. In my case that’s “Parallel Studies” in the color #28ae7b, from the original black (I’m adding screenshots because my blog has a password).

But the published version remains black, even though the tagline (“space, blah, blah”) is displayed in the color I want.

I’ve tried restarting my laptop and flushing my cache. Thank you so much for any help!
