symmetrical audio equalizer made of 6 vertical columns of stacked rounded rectangles. Each column contains identical segments (same width, same height, same spacing), aligned in a clean grid. Each column is a solid, flat color in this exact order from left to right: red, orange, yellow, green, blue, purple. All segments are uniform in size, with no variation in width, height, or spacing anywhere in the image. The columns are evenly spaced horizontally and centered on the canvas.
