I always thought the fonts on the hanger floor were white to.
I just loaded my monitor's color profile. They are a light yellow gold. But the bad news is if you turn off post lighting, 12:00 completely washes out the floor. Turn back on post lighting, shadows and reflections, the font color stands out nice and gold. I played with turning off things with post lighting enabled and when it got to shadows and reflections, the fonts started fading out. A bit like the icon does in flight at a distance when parts of it get transparent. I'm not sure changing the color of the font will fix this one. It's visibility is tied directly to the lighting effects engine.
