Design System Inspiration of Spendesk

1. Visual Theme & Atmosphere

"Spend smarter with Spendesk." Spendesk is "one complete spend management solution" — procurement, cards, invoices, expenses, approvals, budgets, reporting and pre-accounting — built for finance teams, with the mission "to liberate businesses and people to do their best work". Its guiding principles include "Visibility is fundamental for business growth" and "Simplicity equals adoption". The company is a simplified joint stock company registered in Paris, with its registered office at 51 rue de Londres, 75008 Paris.

The site pairs a carbon ink #191b1b with Spendesk's deep purple #7136ed, an olive-grey neutral it calls "grolive" #f3f4ef, and soft accents — lavender #9477f3, periwinkle #b3bffa, mint #91d69f. Headlines are Roobert, text Inter.

What makes it worth reading:

• Three named brand colours. --brand-carbon, --brand-deep-purple, --brand-grolive — ink, action and ground.
• A wide supporting palette. --color-tp-*: purples from ultralight to ultradark, pinks, teal, salmon and a set of greys.
• Restrained buttons. The measured buttons hold their colour on hover.

Primary tasks

• Book a demo; log in.
• See pricing and customer stories.

2. Color Palette & Roles

Measured with getComputedStyle on spendesk.com/en: 194 root custom properties — --color-* 28, --sp-* 27, --fs-* 25, --br-* 23, --space-* 20, --lh-* 15, --neutral-* 10 … All first-party.

Brand

• Deep purple (#7136ed) — --brand-deep-purple; Book a demo.
• Carbon (#191b1b) — --brand-carbon; text.
• Grolive (#f3f4ef) — --brand-grolive; secondary buttons and sections.

3. Typography Rules

Font family

Roobert (500, 600) for headlines and Inter (variable) for text; both load (document.fonts).

Scale

H1 64px/500 Roobert; H2 48px/500; eyebrows 14px/600 uppercase Inter; buttons 16px/600.

4. Component Stylings

Measured with a hover counted only when :hover matched; consent denied. Focus showed only the browser's ring and is not recorded.

• Primary — Book a demo: #7136ed, white 16px/600, 8px, 44px. Hover and press: no change in the button's own values.
• Secondary — Login: #f3f4ef, #191b1b text, a 10% carbon border, 8px, 46px. No hover change.

Radius

8px on buttons.

5. Layout Principles

• A white header with navigation and the two buttons, a hero with a large Roobert headline, then product sections on grolive and lavender.

6. Depth & Elevation

Flat; colour blocks separate sections.

7. Do's and Don'ts

Do

• Use deep purple #7136ed for the main action, carbon for text, grolive for quiet surfaces.
• Keep accents soft — lavender, periwinkle, mint.
• Set headlines in Roobert.

Don't

• Don't use pure black; the ink is carbon #191b1b.
• Don't use pure grey for neutral surfaces; grolive has an olive tint.
• Don't invent hover colours; the measured buttons hold their colour.

8. Responsive Behavior

Not measured. Desktop 1440×1000 only.
