Tag colors in Ventura have changed for the worse

This is what my tags look like on a 2017 5K iMac with Ventura and with Increased Contrast and Reduce Transparency enabled in the Dark Mode and the display set to the SRGB IEC61966-2.1 color profile:

In case you have some 3rd party software that might be interfering with the rendering of the colors try the following: boot into Safe Mode according to How to use safe mode on your Mac and test to see if the problem persists. Reboot normally and test again.

NOTE 1: Safe Mode boot can take up to 3 - 5 minutes as it's doing the following; 

• Verifies your startup disk and attempts to repair directory issues, if needed

• Loads only required kernel extensions (prevents 3rd party kernel/extensions from loading)

• Prevents Startup Items and Login Items from opening automatically

• Disables user-installed fonts 

• Deletes font caches, kernel cache, and other system cache files

NOTE 2: if you have a wireless keyboard with rechargeable batteries connect it with its charging cable before booting into Safe Mode. This makes it act as a wired keyboard as will insure a successful boot into Safe Mode.

I duplicated your settings and the colors were correct...until I disabled Dark Mode. So, for correct colors to display you need to have either Settings >Accessibility >Display >Increase Contrast = OFF, or Increase Contrast = ON *AND* Dark Mode = ON.

BTW, this seems to affect only file Tag and Apple Mail message Flag colors, which I use a lot.

Apple Help says: "Increase Contrast - Increase the contrast of items on the screen (such as borders around buttons or boxes) without changing the contrast of the screen itself."

It appears Apple lumps Tags and Flags into the same 'object type' as "borders around buttons and boxes" and treats them the same. They should operate separately on these object's display colors.

I'd definitely call it an MacOS "bug", certainly not a desirable "feature." I want Increased Contrast (no Dark Mode), but with the correct colors still displayed. From the other various posts, other users do too.

My Tags in Ventura.

I remember seeing another post by someone having an issue with Tag colors. Unfortunately I didn't follow the thread to see what may have resolved the issue. You might want to search these forums.

Then turn off >system settings >Accessibility >Displays > Increase Contrast and your colors will return to their bright and wonderful hue. Problem solved!

It works. But then I much prefer increased contrast for text, so I'll just get used to 'no yellow- brown.'
