This theme is only for CM13 & other Marshmallow ROMS supporting CMTE.
As we don't have CMTE for Nougat yet, all we can do is wait, or use Substratum instead ?

To get this theme on Nougat or Marshmallow supporting Substratum (Legacy or OMS, check your rom for support)
visit https://play.google.com/store/apps/details?id=substratum.greyce.pc

A simple minimal light theme with 3 variants,
Greyce
Greyce Blacks - All the greys from the stock variants are blacks (Still a light theme)
Greyce Pixel - Pixel accent, Greyce style.

Theme is compatible with almost every Marshmallow ROM supporting CM Theme Engine
To get access to the other two variants, you need Arcus

*** If you face any theme related issues after updating, then reboot your device ***
