Four identical speedometer icons arranged in a 2x2 grid, each displaying a gradient from green to yellow to red, indicating speed levels, set against a clean white background. The sleek, modern speedometers feature curved gauges with a dark gray needle pointing toward the yellow zone, segmented into three color-coded zones: green for low speed, yellow for medium, and red for high. Each needle originates from a small black pivot point, rendered thin and tapered, with subtle drop shadows beneath providing gentle depth. Vector-based graphics ensure crisp, flat two-dimensional lines, ideal for infographics or UI design. Lighting is even and diffused, with full-color, saturated palette and no harsh highlights. The minimalist, professional style conveys technological precision and clarity, balanced symmetrically across a square 1:1 composition. High-resolution, artifact-free image with neutral, informative atmosphere.
