Quick View: you want dark blue for the first four rows.
Dark blue means no cloud cover, very transparent (no haze), excellent seeing (steady skies with no turbulence), and fully dark. For the next two rows, dark blue means no wind and very low humidity. The last row is temperature. Dark blue is super cold (-40°F – -31°F), white is at freezing (23°F – 32°F), and bright orange is moderate (68°F – 77°F).
