For those of you looking for the notifications dropdown highlight color
For some obscure reason, it's shared with imodhilite_backgroundColor.
The more I hunt through these Stylevars, the more perplexed I become. Why this would be shared with a Stylevar described as "Inline Mod Highlight Background Color" is completely beyond me.
My puzzlement doesn't come from the name of the Stylevar. It's that the Notification dropdown, which has nothing to do with inline modification, uses that class.
