It may be because blue materials do not absorb infrared too well. The Hawaiian disaster I am now suspecting was from CO2 infrared lasers from the Space Command facility 30 miles away on a mountaintop. They do research in directed energy weapons there.

The mechanism for this is: atoms in molecules are attached to ech other by bonding forces that act like springs. When light hits these substances it causes the 'springs' to absorb energy and vibrate. If the light is at the right frequency to match the spring resonance, the material absorbs the light energy. Blue is less able to absorb infrared, which one thing CO2 lasers emit.
