The color of the gauges is a physical issue, not a coding issue. The white daytime gauges are not lit up. What you are seeing is white paint illuminated by ambient lighting. The red that you see at night is from red LEDs, which turn on with the headlights. If there is sufficient ambient lighting then you may not see the red even if the headlights are on.
