„RAINBOW“ ist ein Farbglas-Texteffekt, erstellt mit FontVibe KI. Dicke Buchstaben aus massivem Glas, jeder in einem anderen Edelsteinton, die farbige Lichtflecken und Kaustikfächer auf einen hellen weißen Studioboden werfen.

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. A premium greeting card mockup on a white linen surface — the card shows RAINBOW as the main headline in colored glass jewel-tone typography: ruby R through violet W. The card design is clean and minimal, white card stock with the multicolor glass letters as the hero element. A small envelope and ribbon visible at the edge. The carrier communicates: rainbow colored glass font used for luxury greeting cards, wedding invitations, or celebration stationery.
