This is a request not sure if it will ever be granted I know there is monochromatic but that isn’t all white. And yes I also know there is bitter pearl shader from the vault of glass triumph but yet again that isn’t completely all white
-
there like 90 of them in the game or do you mean a single white shader if so knowing bungie you'll have to grind (ridiculous tedious quest) to get it
-
Honors of the nine can be pretty white, but that is not obtainable anymore.
-
I haven't tried it out on too many things yet, but a friend helped me get the Bitter Pearl shader from Vault of Glass a few days ago and that might fit what you're looking for.
-
Trials of the nine shaders are all white.
