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: Alternative logos for dark / light themes
Reminder: You have until this Friday to send in a submission!
We’ve received a lot of beautiful and fun color schemes already, so please keep’em coming!
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
