Rigorous Science

Color of the sky

I know the default will be blue, but just HOW blue, i.e., wavelength in nanometers? I have a world with the following stats:

  • Radius: 4628 km.
  • Mass: .35 Earth (2,09076 x 10^24 kg).
  • Atmospheric Density: .88 Earths.
  • Scale height: 14.63 km.
  • Atm. Composition:
    • N2: 72%
    • O2: 19.6%
    • CH4 (Methane): .04%
    • CO2: .02%
    • Ar: 8.34%
    • Plus trace like ozone, water vapor, etc.
  • Temperature: 299 K (25,85 °C)
  • Solar Insolation: 1.04 (relative to Earth)
  • It orbits a G3V star:
    • Temperature 5,756 K (5,482,85 °C)
    • Peak radiation: 503 nm.

What would be the formula for calculating the exact shade of blue? What factors do I need to keep in mind?
