Optical Illusion Triangle with Rainbow Gradient and Circular Rings #1689536 (License: Personal Use)

This striking image features a central equilateral triangle composed of tightly spaced, vivid rainbow-colored bands that recede inward, producing a strong sense of depth and motion. Surrounding the triangle are evenly spaced white concentric circles against a pure black background, enhancing contrast and reinforcing the illusion of tunnel-like perspective. The composition leverages color gradients and geometric symmetry to engage the viewer’s visual cortex.
