[Tigers] Instrument Illumination color

[Mike Michels]

Just had my speedo rebuilt by Nisonger. They did a nice job, but it came
back with different backlight illumination. All the other gauges are an
amber color. The rebuilt one is bluish green. I'm pretty sure the other
gauges have been rebuilt since new. What is the correct color and does
anybody else have amber backlight illumination or is the greenish white
correct?
