I would really like Opal and its block screens in color, but all other apps (except for camera) in greyscale. If the block screens were in color, it would feel celebratory rather than just part of a drab and deterrent custom UI.
Further context : I use my iphone with color filters enabled (greyscale mode) on specific apps to help me limit distraction when needing to focus. If Opal could integrate this into apps designated as distracting or very distracting, it would eliminate the tedious process of creating automations for each app. I am also unable to make the block screens colorful while in greyscale. I think this would improve my current setup because i use color and its absence as cues for focusing and importance.
