A long, thin, gently S-curved stripe running diagonally from the bottom left to the upper right. The stripe is composed of parallel off-white lines with subtle inner striping, giving it a metallic or inlaid appearance. Along its length are two small, distinct colored highlights: one with a rainbow-like sequence (red, yellow, green, blue) near the lower third, and another with a cyan-green glow further up.
Two large, semi-transparent fingerprint marks, slightly overlapping, rendered in a ghostly gray. The ridges are visible but blurred, as if pressed lightly onto the surface.
Diffuse, organic patches of olive-yellow color, irregular in shape, suggesting age, corrosion, or organic residue. Most prominent in the lower left and as a faint vertical streak on the right.
