The shorter wavelengths of the color spectrum, like blue, easily spread when they reach the atmosphere. That is why a large sky may look blue at noon, when sunlight can shine directly from above. The longest wavelengths materialize on Earth when sunlight reaches more than an angle perpendicular, so its route through our atmosphere can be more extensive. Short wavelengths are essentially filtered by the atmosphere at such a prolonged distance, and only the reddish oranges, oranges and yellows are maintained.
