I've seen web designers modify this via CSS. 

I was hoping for something a little easier (i.e. a setting that I could adjust).  Sounds like that isn't the case.  Thanks for confirming.

While it would require CSS, it would be likely just a few lines. In case it helps, the selector for this element is .banner.context .join-alert. 

In the default theme, it's defined in the theme's format-banner.less attachment.

So, for example, you could give it the same background color as the theme's configured alert color with:

.banner.context .join-alert {
	background-color: -evo-themeconfig-color('stateAttention', 'red');
}

where stateAttention is a configuration option defined by the theme and subsequently changeable by administrators in theme configuration without CSS.

Thank you!  I'll see if this is something I can update.
