Roscoe makes filter material for stage lighting and I use the deep blue and green filters to replicate the color of the light sources that Zone VI and the Aristo VCL 4500 heads use. If you can find the real filters Kodak's numbers are Blue 47b and Green 58. I split filter print and before I got the Aristo VCL 4500 head for my Omega D2 I used those very same filters. The gist of the story is you might buy some of the blue and green filter material and cut it down to the 5.5x 5.5 size you need. Just a thought....
