You are correct about color combinations for reading the gauges, particularly during daylight, but I was talking about what colors are better for preserving night vision when driving at night and watching outside at the road ahead. Whitish gauges background is not the best for night vision. That's why for a scope reticle, if your concern is to preserve night vision, red is your friend, even though some other colors are better at bright daytime.The yellowish along with the red needles aren't exactly the best color combo. Easier to see red needles on the white background.
I have the same white/red needles color combo in my work truck. Doesn't reflect off the windows and is easy to read at a glance.
