Spectral reflection (glossy) vs diffused (matte or flat) makes a big difference in IR absorption.


Color pigment makes a difference, i.e. it might be gray to visible light, but its white to IR.

I ran several "sun light" tests on my gray and didn't see a significant increase compared to white.

I'll repeat these test this weekend if it gets sunny out.
