“RAINBOW” es un efecto de texto Vidrio de Color creado con FontVibe IA. Letras gruesas de vidrio macizo, cada una en un tono joya distinto, que proyectan charcos de luz de color y abanicos cáusticos sobre un suelo de estudio blanco y luminoso.

sculpted as thick solid colored glass letterforms — each letter formed from deep-saturated jewel-tone glass with visible material weight and depth. The glass holds intense color throughout its body: ruby red, sapphire blue, emerald green, amber gold, cyan, or violet — color set by scene context. Top surfaces carry sharp mirror-bright specular highlights; side edges reveal full glass thickness with bright refracted light lines. Internal light scatters creating subsurface color gradients — luminous at the core, deeply saturated at edges. Caustic light patterns (rainbow-edged refraction fans) radiate from letter bases onto surrounding surfaces. Style may range from smooth precision-cut optical glass sculpture (modern) to segmented cathedral stained glass (traditional lead-came divided jewel panes) — determined by font choice. The defining quality: saturated transparent color glowing with transmitted light, like jewels held to sunlight. Square 1:1. RAINBOW as colored glass letterforms perfectly centered, filling 75% of frame width. R=ruby red, A=amber orange, I=golden yellow, N=emerald green, B=sapphire blue, O=indigo, W=violet — each letter a solid jewel-tone glass block in its spectrum color. Bright white studio background with soft overhead lighting. Each letter casts caustic refraction fans in its own color across the white surface below — overlapping red, orange, yellow, green, blue, indigo, violet caustic patterns on the white floor, creating a full rainbow light display. Heavy solid glass sculptures radiating their spectrum colors. Clean, luminous, celebratory.
