If you view your character inventory from the Gear Manager, the Chroma is all gone, example: http://i.imgur.com/epdoLcI.png
The latter also affects 3rd party sites/apps like Destiny Item Manager and Ishtar Commander. (I think) It seems Ishtar moved them to Weapons on iOS, but on Android they seems to be gone.
