+# v2.12.4
+
+### Added
+- Named colors are now supported! Over 900 different common colors names are recognized. A list of color names can be found in [core/_color_data.py](https://github.com/kyb3r/modmail/blob/master/core/_color_data.py).
+  - Named colors can be set the same way as hex. But this can only be done through `?config set`, which means database modifications will not work.
+  - For example: `?config set main_color yellowish green`.
+- New config var `main_color` allows you to customize the main Modmail color (as requested by many). Defaults to Discord `blurple`.
+
 # v2.12.3
