Physiotherapy, chiropractic, podiatry and rehab strength & conditioning. Concepts, dead ends, iteration passes and the final suite, kept visible so the reasoning shows. Use the switcher bottom-right to test every mark against all six palettes and both modes.
Healthcare marks in this register favour symmetry, a single closed line weight and a legible reduction at small size over illustrative detail — the opposite of a spa's soft botanical mark or a law firm's crest. The brief this theme answers is precision and reassurance, so the concepts below start from an instrument a physiotherapist actually uses (a goniometer reads joint angle in degrees) rather than a generic cross or heartbeat line.
An open goniometer sweep — the instrument that reads a joint's range of motion in degrees — cut into a C for Carrock, with the indicator arm reading a specific measured angle. Doubles as a compass bearing: the instrument that told Ordnance Survey exactly where Carrock Fell's trig point stood.
Taken forwardA concrete Ordnance Survey trig pillar, the fell-country marker of a fixed, known position. Correct register (Cumbria, precision, permanence) but it reads as a landmark, not a clinic — a customer glancing at 24px sees a tapered box, not a mark about their body.
Dead end — no bodily registerA gait-cycle pressure line — the trace a podiatrist reads off a treadmill plate — bent into a mark that also reads as a fellside contour. Honest to the trade, but at icon size it collapses into an ambiguous squiggle with no anchor point, and it doesn't carry a wordmark cleanly.
Dead end — illegible under 32pxSquare line caps read as a technical diagram, not a mark — correct information, wrong warmth. No end-tick, so the indicator arm looks like an unfinished ruler rather than a dial being read.
Round caps soften the instrument into a mark; the end-tick reads as a needle meeting a scale. Closer, but the ring and the indicator arm are the same weight — at 24px they fuse into one grey blob and the C disappears.
Ring narrowed and the gap opened so the C reads unambiguously; the indicator arm carries the accent colour and a heavier stroke than the ring, so the two elements separate at any size instead of fusing. This is the working final proportion.
Colour strategy: palette-neutral with a self-sufficient
two-stop gradient. A theme logo ships as a data URL and cannot read
page CSS, so it cannot re-tint itself the way inline currentColor
markup can. The ring and the indicator arm each carry a fixed gradient built
from the theme's own cool-ink-to-rust family rather than any single palette's
brand/accent pair, so the mark holds its own identity and legibility against
all six palettes rather than trying (and failing) to match whichever one is
active. The monochrome variant below uses currentColor and is
therefore inline-only, for contexts that do control the surrounding CSS.
At 24px the ring and arm still separate because the arm carries the accent hue, not just a thinner stroke of the same colour — a weight-only distinction disappears at this size, a hue distinction doesn't. The favicon is a redraw (solid disc, single white stroke) rather than the four-colour mark shrunk, which would fuse into a smear at 32px.
The primary lockup against all six palettes. The mark's fixed gradient is chosen to sit comfortably near — but never exactly matching — any single palette's brand colour, so it never looks like a mismatched sticker.
