Blue is the absolute worst color for LASER shielding.

Blue reflects 450 to 500 n/M. and absorbs all other wavelengths.

We design Multi K.W. D.E.W. optical range assets at about 1000 n/M. (Near infrared.)

Blue would both absorb and have the highest loss tangent at 1000 n/M. Thus resulting in the highest thermal rise.
