“HAPPY BIRTHDAY AVA! MAKE A WISH WISHING YOU A DAY FULL OF CAKE, COLOR & CONFETTI.” 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 vertical birthday greeting card, 4:3. Bright high-saturation sky-blue background with a subtle yellow-to-pink sunlit glow at the upper right, soft multicolour string-light bokeh, scattered paper confetti, and small glossy balloon spheres around the edges. Keep the centre uncluttered. Typography must be exact and fully legible. At top, set “HAPPY BIRTHDAY” in small uppercase rounded display letters. In the centre, set the huge headline “AVA!” spanning 72% of the card width. Build every headline letter as a separate, bold rounded candy-balloon form: extreme spherical pneumatic inflation, hemispherical terminals, ultra-gloss candy lacquer, circular near-white specular highlight at each convex apex, soft contact shadows. EACH individual letter must contain its own complete vertical ROYGBIV gradient: red at the top, orange, yellow, green, blue-indigo, violet at the bottom; never one colour per letter and never one gradient across the word. Apply the same complete vertical ROYGBIV gradient inside each supporting letter, with a thin white edge highlight for clarity. Below the name, place a small white frosted-acrylic ribbon carrying “MAKE A WISH”. At the lower third, show a centered three-tier birthday cake hero prop with white frosting, rainbow drip icing, six tiny lit candles, glossy cherries, warm candle flames and soft golden reflections. Along the bottom, set “WISHING YOU A DAY FULL OF CAKE, COLOR & CONFETTI.” in clear rounded lettering. Use warm sunlight from upper right, ray-traced reflections, shallow depth of field, clean crisp print-card composition, no extra words, no logos, no watermark.
