Hi, Jeremy.
Here are a couple options you may benefit from:
For your specific request, http://www.werunthetrinity.com/wp-content/themes/bridge/css/style_dynamic.css is causing the body color to be #adadad (gray)
If that styling wasn’t in place, http://www.werunthetrinity.com/wp-content/themes/bridge/css/stylesheet.min.css would make it #818181 (darker gray)
We do not provide CSS customization support, per our Scope of Support / Terms.
If there’s a code snippet you’d like me to put some eyes on or something else I can help you with, please update this ticket or create a new ticket if it’s a separate issue.
Thank you very much for your understanding.
If you need some coding help, you may want to ask your developer or reference our documentation and list of known customizers.
