Flat Outline Sticker Icon Design

Create high-resolution illustrations of the [OBJECT] icon in the style of flat outline sticker graphics. The icon should be made entirely of a very fine pure black outline, with no internal filling. Use flat, vibrant [yellow, blue, or pink] to add bold, soft-edged sticker-style outlines around the icon. The result should look like a cartoon-style icon cut from black paper, outlined with bright colors. Do not use any white or filled shapes inside. No gradients, no shadows, no textures. Vector-friendly. Black background. Square aspect ratio.
