@tuxracer I don't see where a color from color.html is used in paper-menu, or paper-menu-shared-styles, so I don't know why this import is needed

[notwaldorf]

Ah, --dark-divider-opacity. I originally thought that was from default-theme.html. My bad!

[notwaldorf]

@tuxracer I think you might need to add this to paper-submenu as well.

[notwaldorf]

Thanks!

(I think the test failures are unrelated, since they're happening on master as well. Opened https://github.com/PolymerElements/paper-menu/issues/63)
