Vibrant 3D Geometric Letter F Logo

A vibrant 3D rendering of the letter "F" composed of four distinct geometric shapes: a red and orange pill-like object at the top, a purple half-capsule on the middle-left, a blue sphere on the middle-right, and a teal half-capsule at the bottom-left. The glossy, colorful elements are set against a stark black background, creating a modern and clean aesthetic.
