Color, and nothing else. No letters, no numbers, no symbols on the spheres — only the complete spectrum of visible light, descending from the Monad through the first polarity, with the gradients flowing unbroken between the spheres. Use the controls to watch the system reveal itself as a closed whole.
The six chromatic spheres carry the complete visible spectrum — red, orange, yellow, green, blue, violet — the entire band of light the eye can see, with no part missing. The paths between them are not colored by separate attribution; each is a gradient flowing from one sphere’s color to the next, so the spectrum stays unbroken across the whole structure. This is the gradient principle made visible: distinct points held within a continuous field.
Above the six, the system does not add more colors. It rises into what precedes color: the first polarity of white and black — the active and receptive, yang and yin, the origin of differentiation itself — and above that the Monad, the undifferentiated unity before any division. Unity, then polarity, then the complete spectrum: a closed descent, with the origin of each stage held within the stage above it. Nothing falls outside the structure. The system is complete in itself.
Flip the scale toggle and watch the closure break. The traditional path colors assign each path a separate hue from its planetary, elemental, or zodiacal attribution — a scattered, heterogeneous set with no spectrum and no order, each color demanding to be decoded. That is an open system: fragmentary, referential, pointing outward. The gradient sphere-scale is a closed one: complete, self-justifying, pointing only to itself and the light above. The first can only be read. The second can be inhabited — which is why the practice is built on it.
