Create a vibrant marketing poster background featuring an abstract gradient of deep blues and bright oranges that seamlessly blend into each other, with soft geometric shapes like triangles and circles subtly overlaying the gradient. Add a faint texture that resembles a canvas to give depth, and incorporate elegant, flowing brush strokes in white to add a sense of movement and dynamism. Ensure there is ample negative space in the center for text placement, allowing for a modern and eye-catching design that captures attention.
