Feature Request: Support for Display P3 Colorspace (Similar to Ghostty's window-colorspace="display-p3")

[Rics-Dev]

Feature Request

I am a user of the Rio terminal and appreciate its performance and customization options. I noticed that Ghostty, another terminal emulator, offers a window-colorspace="display-p3" configuration setting that enhances color vibrancy by leveraging the Display P3 colorspace, particularly on macOS displays that support it.

Would it be possible to add a similar feature to Rio terminal to support Display P3 colorspace? This could improve color rendering for users with compatible displays, making the terminal experience more vibrant and visually appealing.

I’d love to hear if this is feasible or if there are technical limitations to consider. Thank you for maintaining Rio and considering this request!
