nemo 0.20.0

Added

• Background tint. In the nemo look, Settings has a Background tint
  under the accent colour: None for plain greys, Subtle as nemo has
  always looked, or Strong for a cast you notice. The window, cards,
  sidebar and lines take on the accent you chose rather than staying
  teal, and text stays as easy to read at every level. Grey as the
  accent keeps the backgrounds near grey.

Fixed

• Changing the look to or from Material no longer stutters: the text
  now eases from one look to the other like everything else.
