This suggestion is to add 16 new blocks which are opaque to the light engine but rendered transparently.
There would be two crafting recipes for each Tinted Stained Glass:
One Dye plus eight Tinted Glass produces eight Tinted Stained Glass.
One Stained Glass plus four Amethyst Shards produces one Tinted Stained Glass.
This could be nice for decor. The main issue I see is that tinted glass is already quite black, so I'm not sure if it would make sense for dye to add much color to it.
The first recipe is fine, but the second one is really bad. It's worse than both the first recipe and the normal tinted glass recipe (1 glass + 4 amethyst → 2 tinted glass). I think it'd be best to just have the first one — because of how different stained & tinted stained glass would probably look, I doubt people would be converting from one to the other.
