Blackdiasem

Blackdiasem is a 7-limit just intonation scale which contains both a pental blackdye pattern and two septal (2.3.7 subgroup) diasem scale patterns of different chiralities within it. It is constant structure and is a detempering of 19c, and is a direct successor and supposed improvement of the similarly-named Blackdyasem scale.
