The AppSignal logo features a stylized design composed of three interconnected loops or arcs, forming a symbol reminiscent of a three-leaf clover or a triquetra. The loops create a central triangular negative space. The logo uses a single bold color, probably varying shades of blue (due to monochromatic appearance), which adds to its modern and clean aesthetic. The icon's line work is consistent in width, which contributes to its sleek and professional look.
