A quiet Mediterranean staircase descends through whitewashed houses toward a single cobalt-blue door placed slightly right of center above the open sea. The door is the unmistakable focal point, framed by pale limestone walls, restrained bougainvillea, and a narrow strip of cobalt water beyond it. The scene should feel inviting, calm, and full of possibility. Use worn stone steps and a few terracotta pots in the foreground. The staircase forms one continuous leading line through the midground toward the blue door, while the distant sea and soft horizon create atmospheric depth. Diffused coastal daylight creates warm cream highlights and cool blue shadows. Use chalk white, warm cream, cobalt, muted olive, and a restrained terracotta accent. Render as a refined classical oil painting with soft academic realism, visible layered brushwork, luminous watercolor-like transitions, believable weathered plaster and stone, atmospheric perspective, controlled detail, and a clear thumbnail-readable focal hierarchy.
