fixes #2885

CHANGELOG-v3.md

@@ -8,6 +8,7 @@
 ### Changed
 - Fixed a bug where Craft was checking the file system when determining if an asset was a GIF, when it should have just been checking the file extension.
 - `craft\base\Plugin` now sets the default `$controllerNamespace` value to the plugin class’ namespace + `\controllers` or `\console\controllers`, depending on whether it’s a web or console request.
+- Improved the contrast of success and error notices in the Control Panel to meet WCAG AA requirements. ([#2885](https://github.com/craftcms/cms/issues/2885))
 
 ### Fixed
 - Fixed a bug where the Plugin Store was listing featured plugins (e.g. “Recently Added”) in alphabetical order rather than the API-defined order. ([pixelandtonic/craftnet#83](https://github.com/pixelandtonic/craftnet/issues/83))
