Totally agree, I wish there was a mechanism by which you could set a dark-themed icon and a light-theme icon based on which theme was chosen by the user (if you indeed let them choose their own theme).
EDIT: Thanks @Johani for pointing me to this theme component: https://meta.discourse.org/t/alternative-logo-for-dark-themes/88502
3 posts were split to a new topic: Color scheme outputs unexpected colors
Reminder: You have until this Friday to send in a submission!

As per dark material design kind of old, but old is gold. The color layouts are already mentioned did a few changes. A dark color scheme which is easy on the eyes and clear text visibility.
So I have finally gone through the 10 and sent them off - Tried to create a different style of schemes in order to fit most tastes - hopefully they came out ok. Was good fun doing them - tough not using any CSS overrides in some places but hopefully they all work pretty well - they did from what I saw anyhow.
As the contest has ended - I hope more people will share their results 
while we wait for the judges
