# Sify Design System

## Overview

Sify describes itself as: “Technology you use - trending concepts in Data Centers, Cloud, AI that impact everyday lives; know more, learn what's in it for you” The interface is light, built on **White (#FFFFFF)** with **Charcoal (#161616)** text, and **Vivid Yellow (#BDD70C)** as the main accent.

Type is set in **Public Sans**. Headlines run large; body text is 14px. Depth comes from soft drop shadows. Corners are mostly 1px.

Measured from [sify.com](https://www.sify.com/) on November 6, 2026 at 1440×900 and 390×844 from 312 rendered elements. Values are computed styles from the live page, not the original source files.

## Colors

The palette has 11 roles.

- **White (#FFFFFF):** Page background, seen 2 times. Token `background`, CSS `--c-contrast-0`.
- **Charcoal (#161616):** Primary text and headings, seen 21 times. Token `on-surface`, CSS `--c-headings`.
- **Graphite (#2B2B2B):** Secondary text, seen 13 times. Token `on-surface-variant`.
- **Slate (#505050):** Muted text and metadata, seen 7 times. Token `on-surface-muted`, CSS `--c-excerpts`.
- **Gray (#8A8A8A):** Subtle text and placeholders, seen 37 times. Token `on-surface-subtle`.
- **White 23% (#FFFFFF3B):** Translucent fill for cards and controls, seen 1 time. Token `overlay`.
- **Mist (#E8E8E8):** Borders and dividers, seen 18 times. Token `outline`, CSS `--c-separator`.
- **Vivid Yellow (#BDD70C):** Brand color on large areas, seen 14 times. Token `primary`.
- **Near Black (#000000):** Text and icons on primary. Token `on-primary`.
- **Graphite (#272727):** High-contrast fills, seen 1 time. Token `inverse-surface`.
- **Deep Green (#005A00):** Accent in text, fills and borders, seen 8 times. Token `secondary`.

## Typography

**Public Sans** carries the whole interface. Fallback stack: `Public Sans, system-ui, sans-serif`. Other loaded fonts: ts-icons.

- **headline-display:** Public Sans 33px at weight 700, line height 1.2. Page title (h1).
- **headline-lg:** Public Sans 26px at weight 700, line height 1.28. Section headings (h2).
- **headline-md:** Public Sans 21px at weight 700, line height 1.36 (17px on mobile). Sub-section headings.
- **headline-sm:** Public Sans 20px at weight 700, line height 1.36. Card and feature titles.
- **body-md:** Public Sans 14px at weight 400, line height 1.5. Body text.
- **body-lg:** Public Sans 15px at weight 400, line height 1.6. Lead paragraphs.
- **body-sm:** Public Sans 12px at weight 400, line height 1.5. Secondary and small text.
- **label-lg:** Public Sans 16px at weight 700, line height 1.36. Large buttons and tabs.
- **label-md:** Public Sans 15px at weight 500, line height 1.6, tracking 0.02em. Buttons, navigation and labels.
- **label-sm:** Public Sans 14px at weight 600, line height 1.43. Small labels and badges.

## Layout

Spacing does not follow a strict grid: 30% of measured values are multiples of 4px, so match the measured steps rather than rounding to a grid.

- **Scale:** xs 3px, sm 8px, md 15px, lg 18px, xl 36px.
- **Gaps:** 36px is the most common gap in flex and grid layouts.
- **Breakpoints:** 479px, 576px, 600px, 767px, 768px, 1024px, 1025px, 1439px, 1440px.

## Elevation & Depth

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

- `rgba(0, 0, 0, 0.16) 0px 2px 7px -4px`
- `rgba(0, 0, 0, 0.5) 0px 3px 7px 0px`

## Shapes

Most elements use 1px corners. Measured radii, most used first:

- **md (1px):** 52 elements.

## Components

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

- **button-outline (“LOAD MORE”):** transparent fill, #333333 text, 13px/700, 2px radius, padding 12px 16px, border 1px solid #E8E8E8, shadow `rgba(0, 0, 0, 0.16) 0px 2px 7px -4px`.
- **button-outline-hover:** background #161616, text #FFFFFF on hover.
- **button-ghost (“LOAD MORE”):** transparent fill, #333333 text, 13px/700, 2px radius, padding 12px 16px, border 1px solid #E8E8E8, shadow `rgba(0, 0, 0, 0.16) 0px 2px 7px -4px`.
- **link:** transparent fill, #161616 text, padding 0px.

## Do's and Don'ts

- Do use #FFFFFF for the page.
- Do keep text in 4 levels: #161616, #2B2B2B, #505050, #8A8A8A.
- Do use #BDD70C as the brand accent: header, logo and key highlights.
- Do reuse the measured spacing steps (8px, 15px, 18px).
- Do use 1px corners on most elements.
- Don't use #8A8A8A for body text; it reaches 3.45:1 on #FFFFFF. Keep it for large text or metadata.
- Don't introduce new font families beyond Public Sans.
- Don't use #BDD70C for large backgrounds or body text.
- Don't make interface transitions slower than 0.3s.

## Motion

Interface transitions are quick: 0.25s, 0.3s.

- **Easing:** `ease-in-out`, `ease-in`, `ease`.
- **Reduced motion:** the page responds to `prefers-reduced-motion`.
