    With various iterations of the Letter sheet fixture in place, I made some layered paper “art” using metallic paper:

    Metallic layered paper - Pyrotechnics block
    Metallic layered paper – Pyrotechnics block

    That’s the Pyrotechnics quilt block pattern.

    This is the RGBY Subpixel pattern:

    I made the bright Pyrotechnics block in the upper left with art paper that looks bright & cheerful in any lighting:

    Metallic layered paper - art paper Pyrotechnics block
    Metallic layered paper – art paper Pyrotechnics block

    That’s the difference between specular reflectors and Lambertian reflectors.

    I cut the metallic paper face-down in the fixture:
