Eleven signal colors for your page — same Swiss print system, your accent.
Your page still ships as one composition: paper, ink, and a single accent. Now you pick the accent.
Open Settings → Appearance, or deselect a block in the editor to reach the same picker. Presets are tuned for carbon ink on unbleached paper — oxide, amber, ochre, olive, forest, slate, cobalt, indigo, plum, and ink black, plus the default signal red.
The color flows through labels, link styles, and heat maps. No theme store. One system. Your accent.
