Luminous Green Birthday Card

This card features a deep black background with large lime-green “HAPPY BIRTHDAY” lettering centred for instant impact 🎉. The letters have a slightly worn, grainy texture that gives them a tactile, street-art feel without adding extra clutter. Long, sharp shadows fall diagonally from each character, creating a sense of depth like the words are standing up from the surface. The strong contrast between the green and black feels like a late-night celebration, as if the message is being shared between close friends who enjoy a sleek, modern look 🎁. The layout stays focused on the words, with generous dark space around them so the greeting reads clearly from across the room. A thin vertical streak in the same lime-green runs down the left edge, adding an off-centre accent that feels like a quick, confident flourish. The text is all caps, set in thick letterforms, and the shadows angle down and to the right across the black field.
