the walls should be orange, maybe just one of them, maybe the floor, parts of it, the ceiling, a light? How about orange sheets, could the curtains be orange, stained glass? The scent could definitely be the one of orange peel. I would like to hear orange sounds and to look out of the window and to see the sky incredibly saturated, magical. It would be a very nice thing. Really. Very much so.
I would love to wake up to orange and to close my eyes... well, you know...
From time to time it might be a good idea to visit a place with orange soil, or maybe to just put on an orange robe and to beg for rice with a little bowl made out of orange wood...
