I'm making a top quilt and I have heard several schools of thought on what colors to use for the top and bottom based on heat radiance/retention.

I have a top quilt I built many years ago. White inside, dark green outside. The theory being the white would reflect heat back at me and the dark might absorb any heat reaching the hammock during the day.

I hear on some of the forums that dark inside colors absorb body heat during the night, thus retaining better heat.

Is there a good inner and outer color, or is there no difference?

Is there science behind any of this?
