Well, I didn't say it had to do it with everything including logos. But for simple display such as the info screen, it could be done with the song title in one color, artist in another, time in another, etc. And depending on the model of VFD, I'm sure you can do color pixel shading just like the Empeg is doing in greyscale now. Just pick a color for the boot logo, say blue, and set up 4 color per pixel shading. And if it's not possible with a particular model of VFD, then just use a solid color. Some of the logos might not exactly look like Monet's, but it can't be too bad. Not to metion that it's possible to do more gradation with the current VFD, but the developers decided to give us 4 shades to work with since they figured that would be best. And there arn't infinite color VFD, but there are multi-colored VFDs. For examples of Multi-colored VFDs, look at the following links:
