Create a flat, full-frame business card background featuring a serene space, earth, and sky theme. Incorporate elements such as a starry night sky, soft cloud formations, or a subtle Earth horizon viewed from space. Use a calming color palette of purples, teals, deep blues, pinkish-purples, and muted pinks (hex codes: #9062F0, #85CACA, #1C2B55, #E47EC7, #DDA7B5). Blend these colors through gentle gradients and smooth transitions to create a harmonious scene. Focus on creating a design that conveys tranquility and depth. Avoid including any characters, vehicles, buildings, text, or recognizable landmarks. The image should be suitable as a professional business card background. --ar 2:1 --no characters, vehicles, buildings, text, landmarks
