Hey Ryan,

This would require you to make a custom overlay, and in order to do that the best thing to do is download the Default child theme framework from the downloads > themes page if you are not already running a child theme of course. If you are, the following still applies.

You will want to copy the silver overlay to your default-child > styles > overlays folder, rename it i.e fishingcapecod.php, and replace every instance of #A2B4C8, with #2b5762

This way, when running the child theme everywhere the blue appears, you will get your logo’s green. For a reference see Creating a Child Theme, but of course do shout if you need further help!
