🧪 Design Branding Simulation

Every wordless brand mark is built on two decisions: a repeatable geometric structure and a disciplined colour palette. This simulator makes both explicit and interactive. The mark itself is generated from a rotational symmetry group C_n — n identical faceted elements distributed at equal angles around a central hub, exactly the construction behind most abstract logo geometry — with an "organic variance" parameter that perturbs the perfect symmetry so the mark reads as hand-drawn rather than mechanical. The palette is derived from a single base hue using one of five real colour-harmony rules from the HSL wheel (monochromatic, analogous, complementary, triadic, split-complementary), and every resulting primary colour is scored against the WCAG 2.1 contrast formula so you can see, live, whether it would actually pass an accessibility check on a dark brand surface. Rotate the mark in 3D, swap symmetry orders and harmony rules, and regenerate the organic seed to explore how structure and colour theory combine into a finished brand identity.
