Re: COLOR vs TEMPERATURE
During my research, I googled for paints that offered high reflectivity (low absorption) in wavelengths above 800nm (above the visible range).
I did find a couple test reports, but the temperature differences between the normal and the high reflective was only about 5 degrees.
If you find anything, by all means, let me know.
