I have been trying to match the VW blue (without success) since I got my Rio 3 months ago.

I have just received the Medium Lavender from Darkstorm and tried it with both clear and smoke lenses. Although it is close-ish, it is far from perfect especially at night.

I think that the problem is the basic colour of the VFD display. I have tried gels that look exactly the same as the VW blue in "natural" light but in front of the VFD greeny-blue they are never "purpley" (if that is a word !) enough.

I have gone back to the clear lens with a inkjet printed purple colour film that looks OK next to the VW blue, rather than matching, and gives the best visibility in sunlight of any of the others I have tried.
