Currently, the beta allows you to change the button, text, and icon colors, while the background card of the profile remains teal/green. It would be great if we could change the background color as well.

In VRCNext, I currently use the selected button color for both the buttons and the profile card, with a slight color offset for the background. A lot of users on my Discord have said that it looks really good, and it feels like something that is currently missing from both the official VRChat.com website and in game profiles.

It would be a huge missed opportunity not to have this. Please consider adding a background/card color option to the Profile Theme endpoint and implementing it both in-game and on the website.
