“RAINBOW TEXT DIMENSIONAL LETTERING STUDY ARCH / 3D COLOR • VOLUME • LIGHT 01” is a Rainbow text effect text effect created with FontVibe AI. Vibrant multi-color rainbow gradient text effects with smooth color transitions, prismatic light and joyful chromatic typography.

Create a finished 3:4 vertical typographic poster, not a mockup. Render every printed string exactly as quoted. Composition: bright sky-blue celebration space with a sunlit pale-yellow floor plane. A huge 3D rainbow balloon arch is the hero prop, occupying the centre 66% of the frame; it is built from separate glossy spheres in red, orange, yellow, green, blue, indigo and violet, with tiny gold confetti drifting around it. Warm sunlight enters from the upper right, producing hard-edged white specular dots and soft floor shadows; blurred multicolour string lights create bokeh near the upper corners. Top eyebrow, small uppercase cobalt-blue condensed sans serif: “DIMENSIONAL LETTERING STUDY”. Inside the open centre of the balloon arch, the headline is two lines: “RAINBOW” then “TEXT”. Use bold rounded display lettering with extreme pneumatic 3D inflation, hemispherical rounded terminals, ultra-glossy candy lacquer, circular near-white specular highlight on each letter apex. CRITICAL: EACH INDIVIDUAL LETTER contains its own complete vertical ROYGBIV gradient: red at its top, orange upper zone, yellow-green middle, blue-indigo lower zone, violet at its bottom; do not distribute colours across the word. Leave narrow sky-blue gaps between letters and add a clean dark-blue extruded shadow behind each glyph for separation. “RAINBOW” spans 76% width; “TEXT” spans 51% width beneath it. Below the arch, set “ARCH / 3D” in deep cobalt geometric sans serif, widely tracked, centered. At bottom, a small cobalt-blue rounded capsule contains white uppercase text: “COLOR • VOLUME • LIGHT”. Add a small violet circular stamp at lower right reading “01”. Keep generous clean margins, crisp vector-like typography, ray-traced 3D balloons, saturated daylight palette, sharp central legibility.
