INSTRUMENTS
Color theory has measurements.
It barely has instruments.
A measurement hands you a number and asks for trust.
An instrument carries its guarantees with it.
01 · certificates
Illuminant Robustness Certificate
A guaranteed lower bound on palette discriminability across an entire illuminant family.
02 · inverse design
Spectral Palette Designer
Design reflectance spectra whose separation survives changes in lighting and observer.
03 · inverse design
Discrimination Test Designer
Optimizes vanishing-design reflectance pairs for color-vision testing directly from spectra.
04 · inverse design
Adversarial Illuminant Synthesis
Finds a physically realizable light that makes a safe palette confusable.
05 · audits
Colormap Topology Audit
Certifies which features a colormap invented or destroyed, per observer including CVD.
06 · audits
Metamer Atlas
Sample the metamer polytope and map where its shape changes across color space.
07 · audits
Spectrum Provenance Audit
Flags reflectance curves that look interpolated, smoothed, or synthesized rather than measured.
08 · benchmarks
Correctness Suite
Metamer confusion pairs, nine metamorphic relations, and 401 conformance vectors for color code.
09 · certificates
Palette Ceiling
A certified upper bound on how separable any N-color palette can be, worst case across CVD, bracketed by a witness palette.
10 · certificates
Spectral Constraint Oracle
A decision procedure for cross-illuminant appearance: witness reflectance when feasible, named conflicts when not.
11 · audits
Transform Audit
Five behavioral invariants any sane color transform must keep, checked over every cell of a supplied 3D LUT.
12 · audits
Dataset Diff
A forensic diff for spectral datasets: names what kind of change each record underwent and gates the release on it.
13 · certificates
Blend Safety Certificate
The verified convex core of the sRGB gamut in Oklab, inside which any linear blend of colors stays in gamut.
14 · audits
Physicality Audit
A per-pixel certificate of physical impossibility: colors no diffuse surface could show under any declared illuminant.
ONE LIBRARY
Every instrument is an MCP tool.
Two engines, required to agree.
