Reading seteffect colors?

[Yen]

Is it possible to read the red, green, blue, and alpha set on the player by seteffect?
It would be helpful if we wanted to make NPCs that darken the screen while active, but we don't want to remove other seteffects set by weather or levels.

I was thinking about this not too long ago when thinking about how I was going to make torches that illuminate a room. It would be nice if this feature could be added (if it's not already, and I just don't know about it)
