The photos at the comparison site (which are the same photos as when you click on the icons on the order form) already show what the faces look like without the backlit buttons. They are accurate depictions of what the panels look like in various lighting conditions.

The Fluorescent Blue that DarkStorm sent me was only barely blue at all. It was mostly just a clear panel with only the faintest hint of blue color to it. It did not alter the color of the VFD at all, and is (like the clear panel) hard to read in direct sunlight because the non-lit pixels are not darkened for increased contrast. The "edge effect" from the backlit buttons was actually less than what is visible with the "light blue" already pictured on DarkStorm's page.
