Making a Top Quilt: Fabric color selections for heat?

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?

Don´t know much about the science behind it, but having at least one dark(black) side will help in drying a moist/wet quilt - very useful on the trail...
I´ve never really noticed any difference when having a lightly colored quilt/bag, only when in direct sunlight - but that´s not where i sleep YMMW

There was a thread on this ( cant find it to link, does someone know?)

The concensus was that it didn't make any practical difference-the benefits of light/dark largely cancel each other out. I prefer darker kit in general because it dries quicker in the sun.

lighter colors reflect heat and darker ones absorb so it all depends on what you want
