How can I set the header color of multipage apps?

• Goal: I'm trying to set the header color of a new multipage app.

• Steps:

  1. I've created a default header
  2. I deleted everything in the default header
  3. I added a background style to "red" so that I can confirm it's working
  4. It only changes the color of two areas on the left and right of the header (see screenshot)
  5. I even created a brand new "light" theme and applied that to the app, but it makes no difference

• Details: This seems pretty simple, not sure why the header is forced to be this dark blue color. Note: before I deleted the stack that is there by default, when hovering over it, it would show the background color I chose (red). Totally wierd.

• App json export:

  • As a new user, the forum did not allow me to upload the app json

Also, I have no custom css applied:

Found the problem, there was some custom css at the level of the entire retool settings (all apps). Settings -> Advanced -> Preloaded CSS
