Hi,
Here is what Claude said to do.
This is a Planner Registration UI element that's controlled by CVENT's theme colors. Specifically:
To fix the dark background on that box:
- Go to Site Designer > Theme > Colors
- The dark box color is likely mapped to Color 3 (your darkest color,
#253D8F or similar)
- CVENT uses one of the theme colors as the background for system UI elements like this planner checkbox
- Try checking Theme > Theme Styling > Pop-Up Windows - the "Body" or "Window" color may control this
However - this is a system-level planner UI element, not a public-facing widget. CVENT may not expose this for customization through the theme. Based on community posts, some planner-mode UI elements inherit from:
- Color 2 or Color 3 in the theme (for backgrounds)
- Theme Styling > Buttons (for the checkbox area styling)
Workaround if the theme doesn't fix it:
Try changing Color 3 temporarily to a lighter color (like #FFFFFF or #DBE5F2), publish, and test the planner registration to see if the box changes. If it does, that confirms which color controls it. You can then decide on a compromise color that works for both the public site and the planner view.
If no theme color controls it, this is a CVENT bug/limitation - you should submit a support case referencing the Planner Registration Mode's "Send registration-triggered emails" checkbox having unreadable text due to the dark background.
Hope this helps!

Hello @James Rose - thank you for the reply.
The box only appears in the Planner Registration Mode - when I am registering someone from the attendee list.
The text says 'Send registration-triggered emails to the registrant' and had a tick box next to it.
So no it doesn't appear in the payment widget and to the general public, but I would still like to try and change the background colour to white so it can be read.

Hello @Fran Bund,
It is a little tough to read., hence your question. Is that a general question you added to the page or part of the payment widget? If it is part of the payment which payment method is toggled on to show that?
Thank you
