The tongkonan is the ancestor-house of the Toraja people — a boat-shaped saddleback roof lifted onto ironwood stilts, its gable facade densely carved in the four sacred colors of pa'ssura: red ochre, soot black, lime-paste white, and turmeric yellow. Every panel encodes lineage, status, and cosmological orientation.
This design system translates the tongkonan's material vocabulary into digital interfaces: soot-black grounds evoking dusk over a Tana Toraja ridge, red ochre panel accents, carved-line borders, and the warm tonal ladder of bamboo bark, ironwood, and buffalo horn.
通科南是托拉查人的祖屋——船形鞍背屋顶高架于铁木桩上，山墙立面密布着帕苏拉四色浮雕：红赭石、烟黑、石灰白、姜黄。每一块雕板都铭刻着世系、地位与宇宙方位。
本设计系统将通科南的材料语言转译为数字界面：以烟黑为底色重现塔纳托拉查山脊黄昏，以红赭石做面板重音，以雕刻线条为边框，在竹皮、铁木与水牛角的暖色阶梯间构建层次。
