Speculations, the green for Loki Scepter (scepter, not ceter) may be right (its the closest), but wasnt proven atm. Same with what Aether and Loki Scepter represents. Only Tesseract and Orb were specifically stated to be Space and Power Stones, respectively. What the yellow and orange Infinity Stones will be, and when they will show up, no one knows.
