Highlight Colors using FM and not the OS

[Christoph]

Hey folks,

I have a three-part question but all related.

1. I understand that when highlighting text in any field, the color is based on the operating system's settings (in my case, Mac's System Settings, Appearance). Can I use Filemaker to force and set the desired color rather than the OS's settings?

2. See the image with the calendar, can the highlighted box have the same "Corner Radius", just like the field?

3. See either image, can the text turn to white, only when it is highlighted?

As always, many thanks!

It would not seem these elements are not customizable, from a developer standpoint.  Claris would have to refine the interaction here, or add selection definitions to the theme. Especially in consideration with Day/Night mode.

I had a feeling they may not be customizable. Thanks for the info, Ocean West.
