Six tones. One secondary. Eight brights.

Cream paper. Ink type. One accent for CTAs, one secondary for headline accent words on light grounds. Plus a stress range for campaigns and partner surfaces. The mark inherits currentColor on every one of them.

§1.5Secondary · headlines on light onlySpring green at display size loses contrast against bone and paper. Canopy is the structural swap — same hue family, dark zone — used only for headline accent words on light grounds. Never on ink or dark.

§3.0Hex referenceAll 15 tones with hex, role, and usage note.

Bone

#F7F2E6

Primary · paper

Default surface everywhere. The cream the rest of the system lives on.

Ink

#1A2418

Always · type

Body text, the wordmark, the icon — unless the surface is dark.

Spring green

#A5E857

Accent · only

The one accent. CTAs, highlights, the yes moment. Pairs with ink — never use as headline type on bone or paper (fails AA at display sizes).

Paper

#FBF8EE

Surface · 02

Inside cards, raised ground against bone.

Sage

#DDE6C8

Support · rare

Quiet UI states, alt cards. Used sparingly.

Flame

#E98A3A

Alarm · only

Destructive confirms, errors. Never decorative.

Canopy

#3F7A1C

Secondary · headlines

Headline accent words on bone or paper only. Spring green at display size fails contrast against cream; Canopy is the same hue family dropped into the dark zone so it reads as type. Never on ink or dark grounds — Spring keeps that lane.

§4.0RulesHow the palette stays a palette.

Use Bone as the default surface. Ink as the default ink. That is 90% of every screen.
Reserve Spring green for CTAs and one accent per dark composition — never as headline type on bone or paper.
When a headline needs an accent word on bone or paper, use Canopy. Same hue family as Spring, darkened to pass AA at display sizes.
Let the mark inherit currentColor — Ink on Bone, Bone on Ink. Never set a fill.
Reach for Flame only when something is breaking — destructive actions, errors.

DON'T

Don't gradient. Two colors blending into each other is never on-brand.
Don't recolor the logomark — no Spring green spiral, no Flame spiral, never.
Don't put Spring green on Spring green or any tone-on-tone field stack.
Don't paint headline accent words in Spring on bone or paper — Canopy is the legible swap.
Don't use Canopy on ink or dark grounds — that's Spring's lane.
Don't extend the palette past these seven tones. Brights are for campaigns only.
