Brand Guidelines

Colors

All values are hex, converted from the source OKLCH tokens. Build on a neutral base and use a single accent per surface — never a rainbow.

Core neutrals (Light / Dark):

Token	Light	Dark	Use
Background	#FFFFFF	#0A0A0A	Page background
Foreground	#0A0A0A	#FAFAFA	Primary text
Card / surface	#F3F3F3	#171717	Elevated surfaces
Muted surface	#F5F5F5	#262626	Secondary surfaces, fills
Muted text	#737373	#A1A1A1	Secondary / supporting text
Border	#E5E5E5	#27272A	Hairlines, dividers, outlines
Input	#F2F2F2	#262626	Form field fills
Ring (focus)	#A1A1A1	#737373	Focus rings
Primary	#171717	#E5E5E5	High-emphasis fills / buttons

Brand accents (pick ONE per surface):

• Blue: #2B91F7 — primary semantic accent
• Yellow: #CCA300
• Orange: #D18B19
• Green: #8AD693
• Purple: #AB80D6
• Red: #F14B4C

Chart ramp (data visualization only): #FFD230 → #FE9A00 → #E17100 → #BB4D00 → #973C00

Destructive: #E7000B (light) / #FF6467 (dark)

Typography

• Sans (headings & body): Roobert — fallback to Inter, then system sans; never serif or decorative display
• Mono (code & product nouns): Roobert Mono — kortix.yaml, sessions, CLI, paths, identifiers; fallback to system mono
• Weights: Regular, Medium, Semibold only (2–3 per surface); avoid Light at small sizes and Black except hero covers
• Scale: Hero 56–72px / 40–54pt · Display 36–48px / 28–36pt · Heading 24–28px / 18–22pt · Body 16px / 11–12pt · Caption 12–14px / 9–10pt
• Note: Roobert should be pre-installed for best results; it falls back cleanly to Inter when unavailable

Tracking & leading:

• Tracking: 0em (normal) is the default for body and most UI. Apply tight tracking (-0.01 to -0.02em) only on hero / large display type. Never loosen body tracking.
• Leading: Headings 1.15–1.25× · Body 1.5–1.6× · Caption 1.4×. Keep body measure 45–75 characters.

Logo

Do not invent marks, alternate wordmarks, or decorative lockups.

Rules:

• 16:9 layouts (slides/covers): use the Kortix symbol only, placed top-left. Use the full logo (symbol + wordmark) only when the full logo is explicitly requested.
• Light surfaces: recolor fills to near-black #0A0A0A. Prefer the symbol alone unless the layout needs the full wordmark.
• Dark surfaces: use white fills #FAFAFA. Never place the white logomark on light backgrounds.
• One mark per surface — same placement discipline as accents (no competing logos).
• Recoloring: edit fill/stroke/currentColor to #0A0A0A or #FAFAFA; never substitute a different shape.

Spacing & Radius

• Spacing unit: 0.23rem base (--spacing). Build gaps and padding as multiples of this unit for consistent rhythm.
• Radius: 0.625rem (10px) base (--radius). Use md for cards and controls, lg (≈1rem) for large panels and covers.
• Border width: 1px everywhere; rely on the border token, not heavier strokes.

Shadows

Shadows are subtle only — low opacity, small offsets, no glow or neon. Shadow color: #1A1F2E (light) / #000000 (dark).

Level	Offset / blur	Opacity
2xs/xs	0px 1px 2px	0.02
sm / —	0px 1px 2px + 0px 1px 2px -1px	0.04
md	0px 1px 2px + 0px 2px 4px -1px	0.04
lg	0px 1px 2px + 0px 4px 6px -1px	0.04
xl	0px 1px 2px + 0px 8px 10px -1px	0.04
2xl	0px 1px 2px	0.10

Motion

Animate with purpose — fade, slide, or product-reveal only.

• Durations: fast 100ms · normal 150ms · moderate 200ms · slow 300ms · slower 500ms
• Easing: default cubic-bezier(0.2, 0, 0, 1) · in cubic-bezier(0.4, 0, 1, 1) · out cubic-bezier(0, 0, 0.2, 1) · in-out cubic-bezier(0.4, 0, 0.2, 1)
• Default pairing: 150–200ms with ease-default for most UI transitions.

Features

Smart Font Application

• Applies Roobert to headings and body (3–4 text styles max per surface: title, heading, body, caption)
• Applies Roobert Mono to product nouns, paths, commands, and config snippets
• Automatically falls back to Inter / system sans if Roobert unavailable
• Preserves readability across all systems

Text Styling

• Hero / cover: Roobert Semibold, tight tracking, one per cover
• Headings (24px+): Roobert Medium or Semibold, leading 1.15–1.25×
• Body: Roobert Regular, 16px floor, leading 1.5–1.6×, measure 45–75 characters
• Smart color selection: neutral surfaces with one meaningful accent
• Flush-left / ragged-right; no justified body; preserve hierarchy

Shape and Accent Colors

• Neutral (black/white/gray) surfaces with one accent per artifact
• Non-text shapes use a single chosen accent from the palette above
• Semantic colors (error, chart ramp) only when content requires them
• Subtle shadows only (see scale above) — no glow or neon

Technical Details

Font Management

• Uses system-installed Roobert and Roobert Mono when available
• Provides automatic fallback to Inter / system sans, and any mono for code
• No font installation required for drafts — works with fallbacks
• For best results, pre-install Roobert and Roobert Mono in your environment

Color Application

• Uses hex/RGB values for precise brand matching
• Light mode: background #FFFFFF, foreground #0A0A0A, border #E5E5E5
• Dark mode: background #0A0A0A, foreground #FAFAFA, border #27272A
• See Spacing & Radius, Shadows, and Motion above for the rest of the token system

Voice (copy on branded artifacts)

• Direct, product-grounded; concrete nouns: sessions, repos, sandboxes, skills, change requests
• Banned: "unlock productivity", "AI transformation", "seamless", "revolutionary", and other generic SaaS claims with no mechanism
• One audience per sentence; lead with real product proof, not abstract AI art
