“SPECTRUM IRIDESCENT TEXT EFFECT · FONTVIBE” is a Holographic text effect efeito de texto criado com a IA da FontVibe. Letras sans serif arredondadas com superfície de folha iridescente que muda entre violeta, ciano, rosa e dourado, com reflexos brilhantes num chão escuro e pequenos pontos de luz.

rendered with iridescent holographic foil effect — multi-layer diffractive film surface producing rainbow spectral shifts across the letter faces, cycling through deep violet, electric cyan, hot pink to warm gold as viewing angle changes, like light diffracting through a stacked polymer security foil. The color shift is the result of structural interference, not pigment: each hue blooms and fades with directional light. Semi-transparent depth visible through the letter surface — background bleeds through with slight chromatic distortion. At all letter edges, rainbow chromatic fringe dissolves outward into scattered prismatic light particles, softening the hard boundary between letterform and space. Fine diffraction grating micro-texture across the surface. Pure black background. Directional overhead light source. Wide cinematic 16:9 composition on pure black background. Center dominant: 'SPECTRUM' as massive holographic foil letters filling 75% of frame width. Letters show vivid rainbow diffractive shift — hot pink at left bleeding through violet to electric cyan to gold at right. Fine diffraction grating texture visible. Bottom strip: small label 'IRIDESCENT TEXT EFFECT · FONTVIBE' in thin clean sans-serif, 40% frame width, centered below main word. Background: pure black with prismatic light scatter fanning from letter surfaces. Studio key light from upper-left. Dazzling holographic energy.
