Choosing a color scheme is a visual decision, so we should do better than describe it with mere words like we do now:
Slack does this very well with their sidebar themes:
Perhaps there’s a simple way to automagically create these types of thumbnails using techniques similar to The Official Discourse Styleguide Plugin?
With all these new schemes coming, this would be a nice addition.
I believe there could be a lead: https://github.com/csquared/IMGKit
Yes that would be awesome cc @sam @awesomerobot @Johani – we should have this ready after the color theme contest!
The first step here would be to add this to the wizard, agree we should wait till the competition is done and then add 6-9 of the best options to a wizard step.
After wizard is done we can think about /admin which has a lot more edge cases.
Ah yes great idea, then they can simply run /wizard if they want to change color schemes. Perfect!
Wizard is done! 
But this work probably needs to be preceded by: Color schemes should be specific to a single theme
