Hi Jay. I picked up two disks of white/pearl and frost 3mm acrylic at the local Plexiglass fabricators.I found the spectrum dominated by green, though. This seems typical of acrylic sheet and used shoe polish/dye to bias the spectrum, based on reading I had done on the subject - not the boot polish, that was my idea. Rub on and polish off to nothing - it worked, providing more blue and red than green.
I guess it depends on the design. Whether you are using LED's or EL panel which tends toward blue. A slim design is an EL panel with diffuser.
