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

I'm not contradicting anyone who has responded but I cannot reproduce what you have reported. I'm running the same release of Word on Sequoia 15.8.2 on an M1 Macbook Pro. This is using the sRGB IEC61966-2.1 Profile.
Have you tested documents in other programs such as Apple's Pages or other text application? I have a feeling that this may be related to Tahoe due to its many other display issues since the Color Picker is a global feature of the OS.
That's the color profile I recommend in my article. There are a few colors that may be off by 1 in R, G or B, but I don't find that this is noticeable.
Please know that I'm not contradicting in any way. My only point was that it doesn't occur here although I can't explain why. I set those values yesterday, closed/reopened several times also created 2nd instance in another program, etc. As this screenshot shows the original 148 R value has held.
My only guess is that the issue was addressed somewhere along the line but for some reason has returned in Tahoe. Whether Apple or Microsoft is to blame I can't say 🫤
This is a peculiarity of PowerPoint for Mac, which is color-managed in Edit (Normal) mode, but not color-managed in presentation mode. Another goofy Microsoft decision.
