Design a calming seascape depicting a solitary sailboat drifting across a vast, open sea under an expansive sky. Capture the gentle undulation of the waves, using soft blues and aquamarines, as the ocean slightly blends with the horizon line where the sky meets the sea. The watercolor technique should allow the colors of the sea and sky to meld in a soothing way, as if the edges are constantly shifting. The sailboat, a mere silhouette imbued with muted details, its sails catching the softest breeze delineated in fine bleeding lines. The sky, a wash of pastel shades, should hint at an impending sunset with colors that ripple across the canvas. Play with light reflections across the water's surface, creating an atmosphere of calm, suggesting the gentle motion of a watercolor-based ocean scene.
