“sadstona” is a Sand Stone text effect FontVibe AIで作成した文字エフェクト. 暖かな砂岩に深く彫ったローマン風セリフ体大文字。V字の彫り溝が琥珀色の斜光をとらえ、岩肌には堆積層の筋.

Text exists as an irreversible physical mark in ancient earth material — carved stone, incised desert varnish, or painted adobe plaster. Not digitally rendered. MATERIAL TRACKS: — Classic Stone / Bas-Relief: warm stone face; iron oxide banding shifts from cream-beige at fresh chisel cuts to amber-ochre across weathered exterior; V-cut groove interiors filled with warm amber shadow; fresh-cut sections reveal lighter stone against darker aged surface — color contrast defines dimensional depth. — Desert Sandstone: amber-ochre to rose-red stone body; horizontal sedimentary grain lines; micro-pitting from wind erosion; fine quartz sand at letter bases. — Petroglyph / Varnish Stone: near-black desert varnish patina on rock; scratch channels cut through to pale tan unweathered stone — high contrast between pale interior and dark patina. — Adobe / Painted Earth: sun-baked buff terracotta plaster; warm red-ochre to burnt sienna pigment; sand aggregate and trowel marks visible through thin paint; hairline drying cracks at pigment edges. STONE LAWS (all tracks): — Low-angle raking sidelight from left at 15–25° grazes every surface — reveals grain, carving depth, micro-texture, patina unevenness. — Geological color palette: cream-beige / amber-ochre / warm sienna / burnt umber / terracotta red / iron brown. No cool tones. — All surfaces carry age: patina, oxidation staining, erosion pitting, mineral banding. — Cut and incised sections always expose lighter, fresher material against dark weathered exterior. FORBIDDEN: neon, digital glow, chrome, smooth modern surfaces, gradient fills, drop shadows, cool tones. When no specific material is defined by the font: default environment — warm amber raking sidelight from lower-left at 20° angle, deep amber-brown shadow pools in surface recesses, dark desert earth background. Archaeological close-up of raw desert sandstone face: 'sadstona' deeply incised into warm amber-ochre stone, letterforms rendered as bold bas-relief cuts biting several millimeters into the rock surface. Low-angle raking sidelight from lower-left at 18 degrees grazes every millimeter of the stone face — fresh chisel-cut groove interiors expose pale cream-beige unweathered stone in sharp contrast against the iron oxide-stained amber-brown exterior patina. Horizontal sedimentary grain lines drift across each letter face and the surrounding field, interrupted only where the carving cuts through strata. Micro-pitting from wind erosion dimples the surface between letterforms; fine quartz sand has drifted into the deepest groove bases. Iron oxide banding shifts from warm buff at clean-cut edges to deep burnt sienna and ochre across the aged exterior. Deep V-cut groove shadows pool as rich warm umber where sidelight cannot reach, defining dimensional depth. Background surface: continuous warm sandstone extending to frame edges, darkening toward the corners as raking light falls off. Geological color palette throughout — cream-beige, amber-ochre, warm sienna, burnt umber, terracotta red, iron brown. No cool tones, no studio light, no digital treatment. Tactile, ancient, irreversible.
