One sheet is light pink with a matte texture, while the other appears glossy and pink. The soft lighting creates shadows emphasizing the different textures of these papers.
A blue circle is filled with evenly spaced horizontal black lines, creating a striped pattern reminiscent of LED modules. The lines make the blue color appear as alternating light and dark blue horizontal stripes within the circle against a white background.
