Themes · replit-deck

Eight complete visual systems captured from replit.com/slides. Each theme is a commitment — once the deck picks a theme, every slide inherits from that theme's token set via <body data-theme="…">. Do not override per-slide.

All hex values were sampled from the actual Replit Slides landing-page PNGs with ImageMagick on 2026-04-29 (see SKILL.md → Scope & provenance). Don't guess, don't substitute "similar" colors from memory. To add or refresh a theme, follow the procedure in Contributing a new theme at the bottom of this file.

How to pick

If the brief mentions…	Pick
SaaS, metrics, board, analytics, fund	helix
law firm, memo, pre-read, confidential, investor note	holm
art, sculpture, photography, catalog, portfolio, gallery	vance
fashion, campaign, lookbook, SS26, jewelry, editorial	bevel
policy, macro, finance report, world economy, dark mood	world-dark
lighter companion deck for a world-dark topic (ESG, wellness finance, sustainability)	world-mint
history, chapter, archive, long-form narrative, museum	atlas
consumer product, real estate, lifestyle, playful	bluehouse

Never mix two themes in one deck. <body data-theme="…"> is the single source of truth for the whole deck — one value, no per-slide overrides. This is enforced as a P0 gate in checklist.md.

If the brief really needs two visual registers (e.g. chapters vs. data), either pick the theme that already carries that internal contrast (bluehouse has gradient cards; atlas has chapter plates vs. data strips), or split the content into two separate decks. world-dark and world-mint are stylistic siblings (same palette, inverted surface), so if you need a companion deck in a different mood they are the most coherent pair — but still one theme per file.

helix — Modern minimal

Reference: replit slide-1, slide-4, slide-5.

--bg       #fafafa   near-white
--fg       #19191c   ink
--muted    #6e6e73
--border   #e4e4e7
--accent   #5889fe   electric blue
--display  Inter Display · weight 600 · tracking -0.02em
--body     Inter
--mono     JetBrains Mono   (bps / YoY labels)

Do

• Huge .num ($1.37B, 128%, 42,850) — dominant element on the slide, no decoration.
• Blue shows up in ▲ 38% YoY / ▼ 1 mo labels only. Use the mono family for those.
• Plenty of white space. Slides often have the content only in the top or left half.
• Page counter bottom-right in mono (03 / 05).

Don't

• No gradients. No card shadows. No rounded accent bars.
• Never put a KPI inside a blue-filled box — blue is type-color only.
• Don't tilt or slant.
• Don't add emoji or icons to metric cards.

Best layouts: kpi-row-6 · split-hero-metric · big-number-center.

holm — Editorial serif memo

Reference: replit slide-2, slide-5.

--bg       #e4dfd7   warm cream
--fg       #0f0f0e   ink
--muted    #7c7e84
--border   #c7c1b7
--accent   #52311d   deep chestnut
--display  Tiempos / GT Super style serif · weight 500
--body     Inter sans (body copy + mono eyebrows)
--mono     JetBrains Mono  (MEMO 04 / APR 2026 style meta)

Do

• Serif display only on the one hero statement per slide. Body copy stays sans.
• Eyebrows (SERIES A — CONFIDENTIAL PRE-READ, 04 — THE ASK) in mono, uppercase, widely tracked, colored by --accent or muted.
• Large vertical rhythm. Think one sentence at 64–96px occupying the left half, the rest breathing.
• A small chestnut wordmark ("Holm") in the top-left meta bar is the only branding.

Don't

• No pure white surface — the cream is the identity. Don't lighten to #fff.
• Don't use the serif for body paragraphs (it will feel like a novel, not a memo).
• No boxed cards. A memo has edges only from whitespace.

Best layouts: memo-hero-statement · two-column-ask · name-card-team.

vance — Gallery catalog

Reference: replit slide-3, slide-7.

--bg       #f1ede2   gallery cream
--fg       #171815   ink
--bar      #0a0a0a   black band (top and/or bottom of slide)
--bar-fg   #f1ede2   cream-on-black
--accent   #171815   ink (there is no chromatic accent)
--display  serif display · weight 400  (italic variants encouraged)
--body     Inter

Do

• Top band holds CATALOG — PLATE NN, II OF V · FEATURED, © 2026 THE ARTIST — always three-column meta in ALL CAPS small tracked type on black.
• The artwork / photo fills the middle plate, edge-to-edge.
• Serif title (Untitled (Threshold)) may break across two lines with italic for the parenthetical.
• Bottom band mirrors top: caption on left (Untitled (Threshold), 2022. Felt, plaster, and resin…), PHOTOGRAPHY — NAME on right.

Don't

• No color accents. Chromatic noise kills the gallery tone.
• Don't center-align text inside the bands — always left/center/right three-column.
• Don't use the cream as a solid background without the black bands; the two-tone is the identity.

Best layouts: gallery-plate · spread-image-quote · index-grid.

bevel — Y2K editorial

Reference: replit slide-6, slide-13.

--bg       #0d0d0b   near-black
--fg       #eae6dd   warm off-white
--muted    #a29e95
--border   #2a2a28
--accent   #c8ff00   neon / chartreuse (outline + dots only)
--display  Y2K display face — Antonio / Bebas / italic chrome sans · weight 700
--body     Inter

Do

• Display wordmark (bevel, reflex) in the chrome-y Y2K italic face — oversized, often rotated off-axis by 0 (but tracked wide).
• Dashed neon frames around product imagery. Each frame gets ::before / ::after neon dots in the corners.
• Small neon square markers (14 PIECES, SS26 INDEX) in the corners.
• Product imagery treated as lookbook: desaturated on black, caption under image in serif-italic small caps.

Don't

• Never fill anything with neon. Neon is outline, dot, or 1-char accent only. More than ~2% neon by area = slop.
• Don't use photography that looks like stock SaaS. If the brief is SaaS, pick a different theme.
• Don't use sentence case for the display wordmark.

Best layouts: campaign-cover · product-triptych · index-grid.

world-dark — Finance dark

Reference: replit slide-8, slide-10.

--bg       #0d3a2b   deep racing green
--fg       #bcd6cd   mint text
--muted    #789f91
--border   #1d4c3c
--accent   #e8f615   neon yellow
--display  Inter Display · weight 500
--body     Inter

Do

• Big sans display for the report title (World Finance Report, Monetary Policy).
• Neon yellow appears as:
  • a small square marker (14×14px) near section breaks,
  • the color of section labels (Total debt, S&P 500) above the dark green cells,
  • never as a fill for a text block.
• Horizontal divider lines are 1px hairlines in --border.
• Image tiles (portraits, skyline, streetscape) use tall 2:3 aspect, full-bleed, with captions in white overlaid bottom-left.

Don't

• No icons in KPI cells.
• Don't use the yellow for links or CTAs — it is a pointer, not a button.
• No rounded corners on dividers or cells.

Best layouts: finance-hero-grid · quadrant-policy · indicator-strip.

world-mint — Finance light (sibling)

Reference: replit slide-9.

Exact mirror of world-dark: swap --bg with --fg. Deep green becomes the type color; mint becomes the surface. Yellow accent stays identical.

Use world-mint as a standalone deck when the topic is gentler (ESG report, wellness finance, sustainability). If a world-dark deck wants a lighter companion piece for a separate audience, make it a separate deck file with data-theme="world-mint" — do not alternate slides inside one deck (see one-theme rule above).

Do / Don't: same as world-dark.

Best layouts: section-divider-giant-title · quadrant-policy · indicator-strip.

atlas — Museum chapter

Reference: replit slide-11.

--bg       #111010   near-black
--fg       #e7e6e2   ivory
--muted    #827d78
--border   #2a2826
--accent   #de3f40   vermilion
--display  serif display · weight 500
--body     Inter

Do

• Vermilion dot (●) before THE ATLAS QUARTERLY · CHAPTER 01 in the meta bar.
• Huge serif titles split across 2 lines (The Imperial / Age.) — the period is always vermilion.
• Three-column data strip at the bottom: PERIOD / REACH / CAPITALS, labels in mono all-caps small, data in sans display (one word per column if possible).
• Right half often carries an archival photograph inside a thin ivory hairline border with PLATE I label top-left and EXHIBIT 04.B tag top-right.
• Progress bar at the very bottom (vermilion segment + ivory hairline).

Don't

• Never use the vermilion for body text or callouts — only for the terminal period, the meta dot, and the progress segment.
• Don't pair the serif with a mono kicker that's larger than 12px; the mono must always feel like a catalogue footer.
• Avoid images with modern styling (filters, gradients). Archive-grade black & white or sepia only.

Best layouts: chapter-plate · timeline-strip · photo-with-caption.

bluehouse — Consumer card

Reference: replit slide-12.

--bg       #0b1524   deep navy
--fg       #ffffff
--muted    #8ea0b8
--border   #1a2c46
--accent   #fb675d   coral
--accent-2 #ff8f68   peach (for gradient)
--card-peach     #e0af99
--card-lavender  #c7cff0
--display  Inter Display · weight 700 · tracking -0.025em
--body     Inter

Do

• Big bold sans headlines (Driving real estate ROI with prime properties) with an inline pill highlighting a key noun (e.g., ROI) — pill uses --card-peach or --card-lavender background with navy text.
• 3–4 cards below in a horizontal row, mixing:
  • one photo card with a subtle tint overlay,
  • one coral→peach gradient card with the hero stat (+47%),
  • one cool lavender→blue gradient card with a secondary stat,
  • one navy / peach neutral card for small numbers.
• Cards are border-radius: 24px, 4:3 aspect, label top-left, number/stat bottom-left.
• Tiny icon cluster top-left of gradient cards (e.g., property-pin chips overlapping).

Don't

• Don't use the coral for headline text. It lives inside gradient cards.
• No more than one gradient direction per slide (either 135° coral→peach OR 180° lavender→blue, not both on the same card).
• Don't put text over the photo area that's smaller than 16px — the imagery competes.

Best layouts: pill-headline-cards-row · product-gradient-grid · hero-photo-split.

---

Cross-theme don'ts (all 8)

• No emoji (SaaS trap).
• No hand-drawn SVG people (AI-slop).
• No "aggressive purple gradient" — bluehouse is the only theme allowed to gradient, and only peach/coral/lavender.
• No rounded left-border cards with a hex-shift accent (generic AI card).
• Invented metrics are forbidden. Use — or a muted rectangle when the number doesn't exist yet.
• The display face is a theme setting, not a slide setting. Never mix serif and Y2K in one deck.

Contributing a new theme

If replit.com/slides ships a new template you want reflected here, or you want to propose a fork theme, follow this procedure so colors stay honest (no memory guesses, no "looks about right").

1. Capture the source PNG

Screenshot the replit.com/slides card at 2× device pixel ratio (macOS: Cmd+Shift+4 on a HiDPI display captures 2×). Save as reference-<theme>.png. Crop to just the template card — exclude chrome and shadows.

2. Extract the dominant colors

# Install once (macOS): brew install imagemagick
magick reference-<theme>.png \
  -resize 200x200 \
  -colors 8 \
  -unique-colors txt:- \
  | tail -n +2 \
  | awk '{print $3}' \
  | sort -u

This quantizes to 8 dominant colors and prints their hex values. The top few will be surface / type / border; the rare one is usually the accent.

For a specific point (e.g. sampling the accent from a known pixel):

magick reference-<theme>.png -format "%[pixel:p{420,280}]" info:

3. Map to the 6-token palette

Every theme uses the same 6 tokens plus a display font. Fill in:

--bg         surface (largest area, ≥ 50% coverage)
--fg         type color (largest area inside text blocks)
--muted      secondary text (~40% alpha feel)
--border     hairline dividers, 1px
--accent     chromatic accent (≤ 5% coverage — the rare color)
--font-display  sans / serif / Y2K display — see the three allowed families in template.html

If the source uses two near-identical grays, collapse to one --border. Don't invent new tokens; every theme must map cleanly to this set so data-theme switching stays lossless.

4. Add the theme block

1. Append a new body[data-theme="<name>"] { … } block to assets/template.html in the theme tokens section. Mirror an existing block's token order.
2. Add the theme row to the od.inputs.theme.values enum in SKILL.md (frontmatter).
3. Add a "When to pick" row to the pick-table in SKILL.md and to the table in this file.
4. Write a new ## <theme> — <name> section below (palette block + Do / Don't / Best layouts), matching the shape of the other eight.
5. Add a P1 theme-specific must to checklist.md (one bullet describing the theme's non-negotiable visual tell).
6. Add a row to the reviewer screenshot-mapping table in the PR description so future contributors can reconcile drift.

5. Verify

• Render a one-slide example with the new theme and compare side-by-side with the source PNG. If the --accent looks off, re-sample with a larger -colors count (try 16) and pick the one whose coverage matches the source.
• Add an example-<theme>.html to examples/ if the new theme is visually contrasting from the existing four (helix / holm / atlas / bluehouse). Otherwise a preview via examples/README.md's instructions is enough.
