Heimdall's eyes are naturally orange, he's not using a Stone. In case everyone's forgotten, Sif and Volstagg gave the Collector the Aether to protect because the Tesseract was already in Asgard. Why would they give that one away if they already had, and were keeping, 2 Stones? It was also revealed in a comic that Heimdall was given the Tesseract both to guard it and to use it to rebuilt the Bifrost. While I think that Heimdall is awesome, no one should have to protect more than one Infinity Stone.
