Spectral Profile (8-D)
A brand emits signals across eight independent perceptual dimensions. Drag each bar, or load a canonical brand, and read the profile a cohort perceives. This is an illustration — to measure a real brand from public evidence (with noise floors and cohort resolution), use the Brand Spectrometer.
Why bars, not a radar. The eight dimensions are independent — there is no fixed order and no meaningful area or adjacency between them, so a spider/radar polygon would invent a “shape” that is an artifact of how the axes happen to be placed. Each bar stands on its own, the way the Brand Spectrometer reports a reading. Two different emission profiles can still read the same to a cohort — metamerism (see the metamerism explorable). Each bar here is magnitude only; to add direction, every dimension becomes a vector in the signed profile (strength ⊥ valence — first the bare idea). Read it back through the anchor claims on the CMO path.
From illustration to measurement
This explorable is a sketch of the eight-dimensional profile concept. A real reading is cohort-resolved, triangulated across public artifacts, and reports a noise floor — it declares a difference only when the signal clears it. That is the Brand Spectrometer. For the theory of what the dimensions are and why eight, start from the CMO path on the Guide.
