Joyful Birthday Rainbow Stripe Card

This greeting card features diagonal rainbow-like bands sweeping from the top right to the bottom left, moving through pinks, reds, oranges, yellows, greens, blues, and purples with soft shadows between each stripe for a layered look 🎉. Centred on the front, the message is set in white, with “HAPPY” at the top and “TO YOU” below in simple, modern lettering. The word “birthday” sits between them in a flowing, cursive-style line that feels like a warm note shared between close friends. The contrast between the steady straight-letter words and the looser middle word adds a little spark, like two people laughing together at a party 🎂. The white text stands out sharply against the saturated colour bands, making it easy to read at a glance. Each stripe looks slightly raised because of the gentle shading, giving the design a folded-paper effect. The diagonal bands are evenly spaced and run continuously behind the centred text from corner to corner.
