Overview
Visual Theme & Atmosphere
“We make processes work for people, companies, and the planet.” Celonis was founded in 2011, “bringing Process Mining from academia into the boardroom”; its timeline runs through cloud (2018), unicorn and decacorn rounds, the Process Intelligence Graph (2023) and the Process Intelligence Platform (2024). It counts 3,000+ employees “in Munich, New York, Madrid and 14 other offices”. Its imprint names Celonis SE, Theresienstr. 6, 80333 Munich, registered office Munich.
The site is stark: a black header and hero, white and light grey sections (#f5f5f5, #e5e5e5),
black text, Poppins everywhere, and a single neon green #5cfe50 for the call to action.
What makes it worth reading:
- A foundation system, “fnd”. 127
--fnd-*properties: colour roles (background base → quinary, border low/mid/high, text high/mid/low, semantic success/danger), a 4px spacing scale to 112px, radii 2/4/8px, and a type scale fromparagraph-xstodisplay-s(8rem, −4px tracking). - Motion as tokens. Three motion personalities —
expressive(ease-out),focused(ease-in-out),informative(linear) — each with quick/base/slow durations (.2s/.3s/.45s–.6s). - One accent. Everything is black, white and grey except the neon green.

Brand Narrative
Process mining brought from academia to the boardroom, now sold as process intelligence. The site is as reductive as a process diagram: black, white, grey, and one neon green where you act.
Principles
- Processes work for people, companies and the planet.
- One accent.
- Motion with intent. Expressive, focused, informative.
Personas
Not researched. No persona claim is made from a UI capture.
Colors
Measured with getComputedStyle on celonis.com: 137 root custom properties, 127 of them --fnd-*.
All first-party.

- Accent green (
#5cfe50) —--fnd-color-background-accent-green; Try for free. - Accent secondary (
#04cd24).
Neutrals
- Black (
#000000) — header, inverse background, text high. - Header button (
#1d1d1d) → hover (#4d4d4d). - Canvas (
#ffffff) · Background secondary (#f5f5f5) · tertiary (#e5e5e5) · quaternary (#cbcbcb) · quinary (#767676). - Foreground (
#000000) · Text mid (#666666) · Text low (#8e8d8d).

Typography
Font family
Poppins (400), loaded (document.fonts) with a metric-matched fallback.
Scale
--fnd-typography-*: heading-xxl 6.25rem/−2px, heading-xl 5rem/−3px, heading-l 3.75rem/−1.5px,
heading-m 2.75rem, heading-s 2rem, paragraph-l 1rem/1.375rem, paragraph-m .875rem. Section headlines
render at 80px/400.
Layout
- A black header and hero, then alternating white and grey sections on a 4px spacing grid.
Responsive Behavior
Not measured. Desktop 1440×1000 only.
Elevation & Depth
Flat; hover darkens with an inset shadow rather than a new fill.
Motion & Easing
Tokens: --fnd-motion-duration-{expressive,focused,informative}-{quick,base,slow} (.2s / .3s /
.45s, informative slow .6s); --fnd-motion-ease-expressive ease-out, -focused ease-in-out,
-informative linear.
Values kept in prose
Measured values the DESIGN.md token grammar cannot carry, kept verbatim:
motion.duration-quick:.2smotion.duration-base:.3smotion.duration-slow:.45smotion.ease-expressive:ease-outmotion.ease-focused:ease-in-outmotion.ease-informative:linear
Components
Measured with focus under a real Tab key and a hover counted only when :hover matched. The pressed
state could not be measured (an overlay intercepted the pointer) and is not recorded.
- Try for free —
#5cfe50, black 14px/400, 2px, 40px. Hover and focus lay a 20% black inset (inset 0 0 0 1000px rgba(0,0,0,.2)). - Hero link — Discover our solutions: white 18px. Hover underlines it and fades in a green
#5cfe50::before.
Radius
2px on buttons; --fnd-radius-m 4px and -l 8px elsewhere.
States
Hover: a 20% black inset on the green button; underline plus a green bar on hero links; the header
button lifts to #4d4d4d. Focus: the same as hover plus the browser’s ring. Pressed: not measured.
Live state probe, 2026-10-16 (), button-primary: pressed — shadow rgba(0, 0, 0, 0.2) 0px 0px 0px 1000px inset.
Do’s and Don’ts
Do
- Keep the palette black, white and grey, with neon green
#5cfe50for the one call to action. - Darken hover with a 20% black inset instead of a new colour.
- Pick motion from the three personalities: expressive, focused, informative.
Don’t
- Don’t add a second accent colour.
- Don’t round buttons; they are 2px.
- Don’t put the green behind body text; it is for actions and highlights.
