Theme Color HEX & RGB Codes - Unwanted Shifting by 1pt

I have attempted to add a color palette as Theme Colors, but one of the colors (#94D2FF / R:148 G:210 B:255) keeps shifting to #93D2FF / R:147 G:210 B:255. If I fix the hex code, the RGB code looks fixed as well (and vice versa), but when I hit Save and open the Theme Colors again, it has switched back to #93D2FF. I know this is practically the same color and likely a result of Mac's color management, but it's important to my client that the codes are absolutely correct.

I tried switching my MacBook's display preset to Internet & Web (sRGB) and this didn't help.

I am running PowerPoint 16.114.4 on macOS Tahoe 26.6.2.

    My coworker was able to fix the problem by giving the .pptx file to AI so it manually edited the theme. It reported that the reason for reverting was that #93D2FF was stored in two separate places in the template rather than just one:

    • the theme color slot
    • the template's custom color list

    I'm not sure if the explanation rings true, but this permanently fixed the color code to the correct HEX/RGB values without issue.
