7 colors:
Red - translucent, matching Filener flat red lens
Blue - translucent, matching original factory blue lens
Smoke - translucent, true gray unlike smoked VFD gray
Amber - translucent, matching Filener raised amber lens
Green - translucent, matching Filener flat green lens
Clear - translucent, shows your LED color or your custom button modification
Black - NOT translucent, matching fascia (hopefully)

I will experiment with modifications and may offer additional customized colors. First attempt will be translucent milky white paint and second will be end-glow fiber flourescent colors. No limit to customization potential.
