# CatchyChat Design System

## Overview

CatchyChat describes itself as: “Catchy Chat is the premier platform for free chat rooms and anonymous online chat with strangers. Talk to people online instantly without registration.” The interface is light, built on **Cool Mist (#E7EAEF)** with **Cool Charcoal (#181D25)** text, and **Vivid Orange (#FF7033)** as the main accent.

Type is set in **Bricolage Grotesque** and **Inter**, with **JetBrains Mono** 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 [catchychat.vercel.app](https://catchychat.vercel.app/) on November 7, 2026 at 1440×900 and 390×844 from 394 rendered elements. Values are computed styles from the live page, not the original source files.

## Colors

The palette has 16 roles, plus gradient stops #FF7033, #E64A19, #FF6952, #FF9800.

## Layout

Spacing is mostly on a 4px grid (72% of measured values), with some off-grid steps. Match the measured scale rather than rounding everything.

- **Scale:** xs 4px, sm 8px, md 16px, lg 32px, xl 40px.
- **Sections:** 96px vertical padding between major sections.
- **Gaps:** 8px is the most common gap in flex and grid layouts.
- **Page margin:** 32px on each side of full-width sections.
- **Breakpoints:** 600px, 640px, 767px, 768px.

## Elevation & Depth

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

- `rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0.1) 0px 4px 6px -1px, rgba(0, 0, 0, 0.1) 0px 2px 4px -2px`
- `rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0.1) 0px 1px 3px 0px, rgba(0, 0, 0, 0.1) 0px 1px 2px -1px`
- `rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0.05) 0px 1px 2px 0px`

Hairline rings and inset highlights also appear: `rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgb(255, 255, 255) 0px 0px 0px 0px, rgb(24, 29, 37) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px`.

## Shapes

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

- **sm (8px):** 40 elements.
- **xs (6px):** 24 elements.
- **md (12px):** 24 elements.
- **lg (16px):** 8 elements.
- **xl (24px):** 4 elements.

## Components

- **button-primary (“Sign Up”):** #FF7033 fill, #FFFFFF text, 12px/700, 8px radius, padding 0px 12px, shadow `rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0.05) 0px 1px 2px 0px`.

- **link:** transparent fill, #45556C text, padding 0px.

## Do's and Don'ts

- Do use #E7EAEF for the page and lift surfaces in small steps: #EDEFF2, #F1F5F9, #FFFFFF.
- Do keep text in 4 levels: #181D25, #0F172B, #45556C, #67717E.
- Do reserve #FF7033 for primary actions and key highlights.
- Do set headlines in Bricolage Grotesque with tight tracking (-0.015em).
- Do reuse the measured spacing steps (8px, 16px, 32px).
- Do use 8px corners on most elements; larger surfaces also use 6px, 12px and 16px.
- Don't use #67717E for body text; it reaches 4.11:1 on #E7EAEF. Keep it for large text or metadata.
- Don't introduce new font families beyond Bricolage Grotesque, Inter and JetBrains Mono.
- Don't use #FF7033 for large backgrounds or body text.
- Don't make interface transitions slower than 0.3s.

## Motion

Interface transitions are quick: 0.15s, 0.2s, 0.3s. Longer ambient animations run 3s, 1s, 1.6s.

- **Easing:** `cubic-bezier(0.4, 0, 0.2, 1)`, `linear`, `ease`.
- **Reduced motion:** the page responds to `prefers-reduced-motion`.
