Ive seen it asked a bunch of times in this forums if rectified Left/Right spits out color (it does not, currently it only does gray scale). I have also seen that its on a "low priority" in terms of features the team is working on (according to mods who have answered questions relating to this).
Anyways I just wanted to request StereoDepth to spit out color rectified Left/Right images maybe it will bump up in the priority list.
