Logan (The Scottish Gael, 1831) palette

March 18, 2023 2 min 2 s

DRAFT working palette for Logan transcriptions (data/sources/logan-1831): his colour vocabulary mapped onto the Tartan Register standard shades (data/sources/str-colours). Deliberately small and fully overlapping — every hex is a Register shade — so Logan-derived variants collapse with Register-coded records of the same sett. Name→shade mapping pending review.

And plotted over the fine grid in three illuminance layers — light, mid and dark. Each wheel is one lightness layer plotted in OKLab's own dimensions: the angle is hue — red at the top, then clockwise through orange and brown, yellow, green, blue and purple, the wheel's jog order — and the radius is chroma, with rings every 0.05. The faint grey dots are the fine grid at that lightness; the red dashed line is the dyeable limit. Hover a dot for its code, name and hex. The small dots are the human palette, the full dots this palette's own shades — so you can read how it lands among the named colours.

The shades

Each shade in OKLCh — lightness L, chroma C and hue h (degrees). The small number under each is that axis's fine-grid index: the lattice level, chroma ring and snapped hue angle that together make the shade's grid code.
