# Column Design System

## Overview

Column describes itself as: “The only nationally chartered bank built to enable developers and builders to create new financial services.” The interface is light, built on **Snow (#F6F6F8)** with **Deep Indigo (#111A4A)** text, and **Deep Indigo (#111A4A)** as the main accent.

Type is set in **SuisseIntl** and **Inter**, with **SuisseIntlMono** for code. Headlines run large with tight negative tracking; body text is 14px. Depth comes from soft drop shadows. Corners are mostly 8px.

Measured from [column.com](https://column.com/) on November 4, 2026 at 1440×900 and 390×844 from 333 rendered elements. Values are computed styles from the live page, not the original source files.

## Layout

Spacing follows a 4px grid: 96% of measured gaps and paddings are multiples of 4px.

- **Scale:** xs 4px, sm 8px, md 12px, lg 32px, xl 48px.
- **Sections:** 140px vertical padding between major sections.
- **Gaps:** 12px is the most common gap in flex and grid layouts.
- **Breakpoints:** 374px, 479px, 480px, 640px, 768px, 870px, 1024px, 1112px, 1200px, 1280px.

## Elevation & Depth

Raised elements use soft drop shadows. The most used recipes:

- `rgba(0, 0, 0, 0.05) 0px 4px 8px 0px, rgba(0, 0, 0, 0.1) 0px 2px 4px 0px, rgba(0, 0, 0, 0.1) 0px 1px 1px 0px`
- `rgba(0, 0, 0, 0.1) 0px 1px 2px 0px`
- `rgb(17, 26, 74) 0px 0px 0px 1px, rgba(0, 0, 0, 0.25) 0px 2px 4px 0px, rgba(0, 0, 0, 0.25) 0px 1px 2px 0px`

Hairline rings and inset highlights also appear: `rgba(255, 255, 255, 0) 0px 1px 1px 0px, rgba(87, 90, 100, 0.12) 0px 0px 0px 1px`.

## Shapes

Most elements use 8px corners. Measured radii, most used first:

- **md (8px):** 152 elements.

## Components

Measured from the rendered page. Token values reference the tokens above.

- **button-primary (“Sign up”):** #111A4A fill, #FFFFFF text, 16px/500, 8px radius, padding 0px 16px, shadow `rgb(17, 26, 74) 0px 0px 0px 1px, rgba(0, 0, 0, 0.25) 0px 2px 4px 0px, rgba(0, 0, 0, 0.25) 0px 1px 2px 0px`.
- **button-outline (“Get started”):** #FFFFFF80 fill, #232730 text, 16px/500, 8px radius, padding 0px 16px, shadow `rgba(255, 255, 255, 0) 0px 1px 1px 0px, rgba(87, 90, 100, 0.12) 0px 0px 0px 1px`.
- **button-outline-hover:** background #FFFFFF, text #232730 on hover.
- **button-ghost (“Products”):** transparent fill, #12161E text, 14px/500, 8px radius, padding 8px 16px.
- **link:** transparent fill, #7C7F88 text, padding 0px.

## Do's and Don'ts

- Do use #F6F6F8 for the page and lift surfaces in small steps: #FFFFFF.
- Do keep text in 4 levels: #111A4A, #12161E, #7C7F88, #A9ACB6.
- Do reserve #111A4A for primary actions and key highlights.
- Do set headlines in SuisseIntl with tight tracking (-0.03em).
- Do keep spacing on the 4px grid.
- Do use 8px corners on most elements.
- Don't use #7C7F88 for body text; it reaches 3.71:1 on #F6F6F8. Keep it for large text or metadata.
- Don't use #A9ACB6 for body text; it reaches 2.10:1 on #F6F6F8. Keep it for large text or metadata.
- Don't introduce new font families beyond SuisseIntl, Inter and SuisseIntlMono.
- Don't use #111A4A for large backgrounds or body text.
- Don't make interface transitions slower than 0.5s.

## Motion

Interface transitions are quick: 0.2s, 0.3s, 0.5s, 0.1s.

- **Easing:** `ease`, `cubic-bezier(0.4, 0, 0.2, 1)`, `cubic-bezier(0.76, 0, 0.24, 1)`.
