Ok, I saw the thread about cyan-looking blue. I have an idea. One of the new empegs I received has a different blue lens.
I took a couple of pictures of it and they're up on my site and linked below. The first pic is an untouched shot from the camera (cropped and resized only). The other one I adjusted the hue and saturation of both faces to better match what they actually look like.
The display through the normal BLUE (bottom) lens makes the text look baby blue. But definitely very rich and obviously BLUE. The new oddball lens (top) gives the display an additional green tint, causing it to look more ultramarine or much closer to the colour of the VFD without a lens - a much closer match to that green-blue colour on a lot of stereo equipment and VCRs.

Any offers for the new ultra-rare lens? :)
