Swap colors on Apple Watch GMT face?

I just upgraded to the series 6 Apple Watch and started using the GMT face, which I love except for one annoying issue. Most of the color combinations result in the brighter color being applied to the hours of darkness rather than to the daylight hours when a second timezone is set. So, for example, when I set my second timezone to Tel Aviv (TA) and the color combination to "flamingo", the pink color is applied to the night hours and the gray is applied to the daytime hours. I would *love* it if the ability to simply swap the two colors in existing color combinations were added. Thanks.
