Design Tokens

Last updated on 2026-05-31

The SaaS Metrics Kit uses oklch color tokens defined as CSS custom properties in app/globals.css. All components reference these tokens through Tailwind CSS v4 -- never hardcoded colors. The kit ships with a deep blue-violet theme (oklch hue 260) and a golden secondary accent (hue 71).

oklch Color System

The kit uses oklch (Oklab Lightness Chroma Hue) instead of hex or hsl:

Perceptually uniform -- equal steps in lightness look equal to the human eye, so your palette looks balanced without manual tweaking
Wider gamut -- access to more vibrant colors on modern displays (P3, Rec. 2020)
Easy palette generation -- change one hue angle to produce a cohesive brand palette across all semantic tokens

The format is oklch(lightness chroma hue) where lightness is 0-1, chroma is 0-0.4 (saturation intensity), and hue is 0-360 (color angle on the color wheel).

Color Tokens

Semantic color tokens that automatically adapt between light and dark mode:

:root {
  --background: oklch(0.99 0.002 260);
  --foreground: oklch(0.17 0.02 260);
  --card: oklch(1 0 0);
  --card-foreground: oklch(0.17 0.02 260);
  --popover: oklch(1 0 0);
  --popover-foreground: oklch(0.17 0.02 260);
  --primary: oklch(0.45 0.2 260);
  --primary-foreground: oklch(0.98 0.005 260);
  --secondary: oklch(0.78 0.14 71);
  --secondary-foreground: oklch(0.25 0.05 71);

Dedicated tokens for the dashboard sidebar navigation:

:root {
  --sidebar: oklch(0.97 0.008 260);
  --sidebar-foreground: oklch(0.17 0.02 260);
  --sidebar-primary: oklch(0.45 0.2 260);

  --sidebar-accent-foreground: oklch(0.35 0.15 260);
  --sidebar-border: oklch(0.91 0.01 260);
  --sidebar-ring: oklch(0.55 0.18 260);
}

.dark {
  --sidebar: oklch(0.19 0.025 260);
  --sidebar-foreground: oklch(0.96 0.005 260);
  --sidebar-primary: oklch(0.7 0.18 260);
  --sidebar-primary-foreground: oklch(0.15 0.02 260);
  --sidebar-accent: oklch(0.28 0.04 260);
  --sidebar-accent-foreground: oklch(0.92 0.01 260);
  --sidebar-border: oklch(1 0 0 / 12%);
  --sidebar-ring: oklch(0.6 0.16 260);
}

Chart Colors

Five chart-specific color tokens used by all Recharts components across analytics and management screens:

:root {
  --chart-1: oklch(0.55 0.2 260);   /* Blue-violet (primary) */
  --chart-2: oklch(0.75 0.14 71);   /* Gold */
  --chart-3: oklch(0.65 0.2 146);   /* Green */
  --chart-4: oklch(0.6 0.18 326);   /* Magenta */
  --chart-5: oklch(0.7 0.15 196);   /* Teal */
}

.dark {
  --chart-1: oklch(0.7 0.18 260);
  --chart-2: oklch(0.72 0.14 71);
  --chart-3: oklch(0.65 0.2 146);
  --chart-4: oklch(0.65 0.18 326);
  --chart-5: oklch(0.7 0.15 196);
}

Usage in Tailwind

Tokens map directly to Tailwind utility classes. Use them like standard Tailwind colors:

<div className="bg-background text-foreground border-border">
  <button className="bg-primary text-primary-foreground">
    View Revenue
  </button>
  <span className="text-muted-foreground">Last updated 2 hours ago</span>
  <div className="bg-sidebar text-sidebar-foreground">
    Sidebar content
  </div>
</div>

Charts reference tokens via CSS variables:

<Area
  type="monotone"
  dataKey="mrr"
  stroke="var(--chart-1)"
  fill="var(--chart-1)"
  fillOpacity={0.15}
/>

Dark Mode

The kit uses next-themes with class-based dark mode. The ThemeToggle component handles the switch:

import { ThemeToggle } from "@/components/layout/theme-toggle"

<ThemeToggle />

Dark mode values are defined in the .dark selector within globals.css. All semantic tokens automatically switch when the theme changes. The ThemeToggle component includes proper aria-label text that updates to reflect the current action ("Switch to light mode" / "Switch to dark mode").

Typography

The kit uses three font families configured in app/layout.tsx:

Token	Font	Usage
`--font-sans`	Inter	Body text
`--font-heading`	DM Sans	Headings (h1-h6)
`--font-mono`	JetBrains Mono	Code blocks, invoice numbers

Headings use tighter letter-spacing (-0.025em) and shorter line-height (1.2) for visual weight. Body text uses -0.011em letter-spacing with 1.6 line-height for readability.

Border Radius

The kit uses a base --radius value of 0.625rem with computed variants:

Token	Computed Value
`--radius-sm`	`0.375rem` (radius * 0.6)
`--radius-md`	`0.5rem` (radius * 0.8)
`--radius-lg`	`0.625rem` (base radius)
`--radius-xl`	`0.875rem` (radius * 1.4)
`--radius-2xl`	`1.125rem` (radius * 1.8)
`--radius-3xl`	`1.375rem` (radius * 2.2)
`--radius-4xl`	`1.625rem` (radius * 2.6)

Animation Tokens

The kit includes custom keyframe animations defined in globals.css:

Class	Keyframe	Duration	Use Case
`animate-fade-in-up`	`fade-in-up`	0.5s	Page section entrances
`animate-fade-in`	`fade-in`	0.4s	Element appearances
`animate-scale-in`	`scale-in`	0.3s	Card/modal entrances
`animate-float`	`float`	6s (loop)	Landing page decorative elements
`animate-shimmer`	`shimmer`	1.5s (loop)	Loading state placeholders

Stagger delay utilities (.stagger-1 through .stagger-6) add 100ms increments for sequenced entrance animations.

Customizing for Your Brand

To rebrand the kit, change the hue value in app/globals.css. The default theme uses hue 260. Update it to your brand color and all 25 screens adapt automatically:

:root {
  /* Change hue from 260 (blue-violet) to 150 (green) */
  --primary: oklch(0.45 0.2 150);
  --primary-foreground: oklch(0.98 0 0);
  --ring: oklch(0.55 0.18 150);
  /* Update remaining tokens to match... */
}

.dark {
  --primary: oklch(0.7 0.18 150);
  --primary-foreground: oklch(0.15 0.02 150);
  /* ... */
}

All components automatically inherit the new palette -- buttons, badges, links, charts, sidebar accents, status indicators, and focus rings all update at once.
