Color

Primary palette

Two colors do the work. Green leads; teal supports. Everything else on this page exists to make those two look good.

Swatch Name Hex Where it goes
  Primary green #61A244 The brand stripe, headline accents, large numerals, icons, and fills under dark text. Not for small text on white.
  Accent teal #378494 Hover states, link underlines, chart lines, secondary emphasis. Never the dominant fill on a page.

Supporting greens

When something needs a green background, it gets one of these, not a lightened primary. Dark text on either passes comfortably.

Swatch Name Hex Where it goes
  Soft green #9AC286 Module fills, highlighted rows, secondary cards.
  Pale green #C0DCB4 Tags, icon chips, callout backgrounds, table header rows.

Neutrals

Grey is structure, not voice. Rules, borders, footers, disabled states, and nothing you have to read.

Swatch Name Hex Where it goes
  Ink #231F20 Body text and headings. The site's text color, not pure black.
  Light grey #E4E4E3 Borders, rules, footer backgrounds.
  Mid grey #949494 Disabled states, dashed outlines, icons. Not text.
  White #FFFFFF The ground. Pages are white first.

How to use it

Draft rules. Marketing to confirm before this guide is cited in a review.

  1. Green leads. One primary-green moment per screen: the stripe, the headline accent, the number that matters. If everything is green, nothing is.
  2. Teal supports. Hover, link underlines, secondary emphasis, chart lines. It never becomes the dominant fill.
  3. Fills stick to the greens. Module and card backgrounds use soft or pale green with dark text. Not grey, not teal.
  4. Grey is structure. Light grey for rules, borders, and footers; mid grey for disabled states and dashed outlines. Neither is a text color.
  5. Dark on light. Body text is ink on white or on a green tint. Green and teal are never body-text colors on white. The next section is why.

Contrast, already checked

WCAG AA wants 4.5:1 for small text and 3:1 for large text (24px, or 19px bold) and for UI pieces like icons and borders. These are the brand pairs, computed, so nobody has to guess in a deck at 4:55 on a Friday.

Pairing Ratio Small text Large text and UI
Ink on white 16.3:1 Yes Yes
Ink on light grey 12.8:1 Yes Yes
Ink on pale green 11.0:1 Yes Yes
Ink on soft green 8.1:1 Yes Yes
Primary green on ink (dark backgrounds) 5.3:1 Yes Yes
Accent teal on white, or white on teal 4.3:1 No, just under 4.5 Yes
Primary green on white, or white on green 3.1:1 No Yes
Mid grey on white 3.0:1 No Borders and icons only
Soft green on white 2.0:1 No No. A fill, not a mark

The short version: on white, green and teal are for headlines, numerals, buttons, and icons, not sentences. On a dark ground, primary green reads fine as text, which is why the dark internal dashboards get away with it.

Don't

  • Don't set paragraphs or captions in green or teal on white. The table above is the whole argument.
  • Don't tint the primary green with opacity or gradients. Reach for soft or pale green instead.
  • Don't introduce a green that's "close enough." Four Inc. has three greens and a teal. That is the set.
  • Don't use green-versus-red to mean good-versus-bad in a chart. Use teal and grey, and label the series.
