That said, Lime would do too. The problem I had with Lime is that it happens to be inconsistent. There are places where the color was visibly darker (e.g. in conversations, some confirmation buttons). At least that's my impression (perhaps there are other masks in play here, effectively darking Lime's 'natural' tone etc, which happen to be way less visible with Light Green).

Kebbana, what you've done with #3c3 is the way to do it: use the same color everywhere. Any chance you could update the Lime theme as well to match the color to be the same everywhere? You may think it will be too pale, e.g. in conversations, but that's Lime's magic and I like that.
