The rolling waves crash against the rocks, billowing white foam that upsurges over the jagged crags. The clouds above are swollen and oppressive, the rolling thunder echoing across the harbor. The wind whips the salty sea spray into a frenzy, whipping the sails of the boats to and fro as if in some tempestuous dance. The boats are battened down, their sails rapidly filling and then billowing out as the wind forces them into action. All around is a palette of grays and blues, the jagged rocks standing out amongst the lapping waves and brooding clouds. To bring this scene to life, consider filling the sails with a bright, eye-catching yellow and the sea with blues, turquoise and greens, allowing the moody rocks to be dark in contrast. Bring the scene to life with vibrant colors, allowing the darkened clouds to contrast beautifully with the sails and sea.
