Ceramic Pebble Gradient Gallery Still Life

Present ceramic pebble gradient with a clear hierarchy and a memorable focal point. Glazed ceramic pebbles transition from matte white to deep cobalt across a long stone surface. Emphasize sophisticated form, material behavior, spatial depth, and a deliberate visual rhythm suitable for a premium digital backdrop. Color grading: White, cobalt, pale blue, and stone gray. Design character: Use gallery still-life photography with tactile glaze and disciplined repetition. Give the scene a strong lateral rhythm and arrange the gradient from left to right, cluster larger forms near center, and keep space above. Keep one dominant visual gesture and clean negative space； avoid text, logos, accidental faces, muddy color, and repetitive noise.
