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.
