Cattleya (formerly orchid) is a theme for VSCode that aims to be one you can look at all day. It's contrasty, it's fun, it uses syntax grammars to their fullest (mostly JS and TS since that's what I spend the most time looking at). Note: This extension is a work-in-progress, I'm sure I will find things to change as I work more with VSCode.
What's in a name?
Years ago I created a theme for Adobe's Brackets editor called "orchid". The name was inspired by a gorgeous purple color used prominently within the theme (#DA70D6, aka "orchid"). Since then, as I've moved to other code editors, I've adapted and improved on this theme for whichever editor I'm using at any given moment. I hadn't really given the name much thought since I originally created it. When I was bringing this theme to nova I considered the name again, and landed on "cattleya" because it's an evocative name which harkens back to the original, cattleya being a genus within the orchid family.
