User level: Level 1 (4 points)The Apple Watch Ultra night mode is always in red, and the color blind settings does not appear to change the colors as it used to.
In some update it broke the colorblind settings for night mode as such it's always red.
In the past color blind settings allowed me to give it more of a magenta hue so it was easier for me to distinguish but now none of the color filters seem to do anything to the night mode red hue.

This may actually be expected behavior with Night Mode. Apple says Night Mode on the Ultra’s Wayfinder and Modular Ultra faces turns all elements red specifically to preserve night vision.
Color Filters are available under Settings -> Accessibility -> Color Filters, but Apple doesn’t document an option to override the fixed red Night Mode color.
If this worked differently in an earlier watchOS version, it could be a software change/bug.
