Create a vibrant marketing poster background featuring a dynamic abstract design with bold geometric shapes in shades of blue, orange, and yellow. Incorporate a soft gradient that transitions from a light to a darker shade to add depth. Include subtle textures like diagonal stripes or dots to create visual interest, and leave ample negative space in the center for text or logos. Add faint silhouettes of urban landscapes or natural elements in the background to evoke a sense of context, while maintaining a modern and professional aesthetic.
