The sky is painted with a deep and beautiful blue, with sapphire hues and hints of reflections from the sea. The sun is a huge auburn globe in the sky, growing fainter and softer in color as it sets. The ocean is a deep, dark blue matched by the sky, shimmering like a pool of diamonds in the afterglow of the day. The land is a lush and vibrant green, with ocean-scoured rocks, tall palm trees and other trees contrasting against the mountains in the distance.
I would color this picture in softly blended tones of blues, greens, and oranges to recreate the brilliant light of the setting sun. I would use a paler blue for the shallower ocean, and a darker blue for the deeper ocean. The sky would be a gentle blue with hints of purple and pink in the sunset. The land would be painted with a deep verdant green, with fewer highlights and darker tones underneath trees and in the shadows of the mountains. The sun would be a large orange ball, with bright yellow highlights in the center to illuminate its warmth.
