Steps to reproduce:

1. Launch Thunderbird
2. Make sure your inbox folder is not the selected one
3. Enter your password
4. Receive mail into your inbox folder

Actual results:

The unread message count is shown as #FFFFF text on a #D7D7D7 background, a contast ratio of 1.43:1.

Expected results:

The unread message count is shown as #FFFFF text on a background which provides a contrast ration of at least 4.5:1, for example #757575.

I am on macOS 14.0. I have System Settings, Accessibility, Display, Increase Contrast set to On.

Confirming this bug.

This happens on macOS with:

System Settings, Accessibility, Display, Increase Contrast set to On.

• Thunderbird theme as inherit system theme
• System theme as light

Steps to duplicate:

• Make sure Increase Contrast is set on settings.
• Look at the unread count on folders. For folders with new, unread messages, the gray is too light.

Update: This is for items with new messages.

Noting that the two colors (currently blue and gray) would correctly have a contrast with respect to each other of at least 3:1 to support people with color blindness.

Alternatively, consider using a different shape for new unread unfocused, or using a black outline and black number with white background.

I'm on Windows with the default theme and this seems to be correct now, is this still an issue

Still happening for me in macOS 14.3.1, Thunderbird 115.8.0. I have System Settings, Accessibility, Display, Increase Contrast set to On.

If I turn Increase Contrast off, the issue goes away (but then I no longer have increased contrast throughout my system). I expect Thunderbird to work with Increase Contrast turned on.

I don't know whether Windows has a similar setting, and only use Thunderbird on Mac.

To clarify, I too am using Thunderbird's default theme. It's specifically that it doesn't play well with macOS's Increase Contrast setting.
