Hi Rick,
Ouch that doesn’t look good – I’ve not changed that in a long while.
You can adjust it yourself fairly easily.
Dashboard>Appearance>Customize (More instructions https://www.wpbeginner.com/plugins/how-to-easily-add-custom-css-to-your-wordpress-site/)
Then scroll down and click on Additional CSS
and add the following
.ca-media-list-item:nth-child(even), .ca-series-list-item:nth-child(even){color:rgba(54, 54, 54, 1)!important}
.church-admin-directory{color:#FFF!important}
Then click publish at the top
The first line makes the alternate media lines the site’s dark grey
The second line should make all the directory text white
