This greeting card features the words “HAPPY BIRTHDAY” stacked in two lines and centered on a bright white background 🎉. Each letter is a different strong color, mixing lime green, red, orange, purple, and deep teal for a lively rainbow effect. Where the letters overlap, the colors darken and blend, like translucent layers laid closely together, creating a cozy sense of connection between the shapes. The balanced spacing and even alignment give the layout a steady, friendly rhythm, like two people standing shoulder to shoulder. The text sits squarely in the middle with no border or extra illustrations, letting the color and layering do all the talking 🎂. Bright, even lighting reveals a faint paper grain beneath the design, adding a soft tactile look without distracting from the message. Some letter edges look slightly uneven, which adds a gentle, human touch to the crisp shapes. The overlapping areas form deeper tones—especially where teal meets purple and red meets orange—right across the center of the stacked words.
