C-003290 features a subtly organic, lightly rugged character reminiscent of natural stone or softly weathered concrete. Its cool, muted gray tone is enriched by gentle variations that lend the surface depth and dimensionality. Delicate, irregular patterns drift across its face - suggestive of fine mineral veining or softly interwoven fibers. In certain areas, faint wavelike lines introduce a sense of movement, as if shaped by gradual sediment layering or slow mineral formation. These details remain understated and smoothly blended, creating a serene, cloud-like visual effect that feels both natural and refined.
