Design of a poster with gradient from blue to white background

Quick answer：

The design of a poster with a gradient from blue to white background involves creating a visual composition that starts with a dominant blue color and gradually transitions to white. This technique is often used to evoke a sense of calmness, progression, or transformation. It requires the use of graphic design software to blend colors smoothly across the background of the poster. The design may also include typography, images, or other elements that complement the gradient and contribute to the overall message or theme of the poster.
