Inside / outside colours for TQ & UQ

[Acer]

Jeese,,wished I had thought of the black on the inside for drying purposes,,nice idea!

Perfect, thanks lilricky. I knew there was some science to it.

Black is the best at absorbing infrared energy, however, given the choices of subdued colors that our quilt makers give us, you wouldn't be able to tell any temperature difference. For example the wavelength difference between black and green is only 4%. Now if you were talking about black versus white, it would be a 24% difference in wavelength, which translates to a noticeable difference in the rate of heat absorption in a quilt. So, if you really want that 4% increase in efficiency, go with black on the outer shell. But if you want another color(other than white or possibly yellow) then go for it, you really won't be able to tell.

lilricky, where do you find this stuff? This is why science scares some of us folks.

What a great response
