awesome-mcp-explorer needs six mutually distinguishable colours for its A-F
grades, and the design system had no answer -- one accent, and semantic roles
that deliberately cluster in one hue wedge. Raised as its own decision (per
PHASE3-PROMPT) and resolved by designing the ramp rather than mapping grades
onto success/warning/danger, which would have collapsed six steps into three.
Chosen by search, not by eye, under four hard constraints:
- pairwise CIE dE >= 20 under normal vision AND deuteranopia, protanopia and
tritanopia (worst observed 26.0)
- >= 3:1 against BOTH backgrounds, since the ramp does not re-theme. This is
the binding constraint: such colours only exist in L* 44-59.
- monotonic lightness 58 -> 44, so hue and lightness encode redundantly and
the ramp survives greyscale as an ordinal scale
- muted saturation, to sit with the rest of the palette
scripts/ramp_check.py re-runs the whole proof and exits non-zero on a
regression, so this is a gate rather than a paragraph. A seventh hue is not
available (best candidate reaches dE 17.9); group the tail into "other".
This ramp is the only token group that leaves the warm wedge, deliberately:
hue separation is the entire point of a categorical scale.
Also: tokens.test.ts guards every frozen value against drift, and
tokens.md was split (screen-size.md) to hold the 250-line cap.
