A majestic mountain range at sunrise, with snow-capped peaks towering above the misty valleys below, where a lone hiker is silhouetted against the bright blue sky, with a backpack and trekking poles in hand.

A futuristic cityscape at dusk, with sleek skyscrapers and neon-lit billboards reflecting the vibrant blue hues of the evening sky, while a speeding car zooms down the highway, leaving a trail of blue-tinted headlights behind it.

A serene summer evening sky with a bright blue horizon and a few wispy clouds drifting lazily across it, with a sailboat gliding effortlessly across the calm waters of a nearby lake, surrounded by lush green trees and a few blooming flowers.
