Heat filter is red,and heats photons that pass through to 8000 degrees. Does not change state. Solid
CFLT-Cold Filter
Cold Filter is blue,and changes photons that pass through to -800 degrees. Does not change state. Solid.
These materials could make freeze rays or piercing lasers much easier,and could open up a lot of possibilities other than lasers.
