VFD Coloring Display

In opposite to LEDs the VFDs have a wide spectrum of visible light. Without of any filter the display shows a blueish green. With a filter foil the look can be shifted in many directions.

A cheap way are filter foils for stage and video lighting. Here some examples:

Filter foil	Effect	Comment
without	blueish green
LEE 101 - yellow	old monitor green
LEE 105 - orange	old monitor amber
LEE 118 - light blue	cyan
LEE 180 - dark lavender	blue
LEE 122 - fern green	warm green
LEE 106 - primary red	red
LEE 111 - dark pink	white
LEE 107 - light rose	greenish white
LEE 008 - dark salmon	warm white
LEE 779 - bastard pink	orange white
