Use when no template or reference presentation is available.

Design Ideas

Don't create boring slides. Plain bullets on a white background won't impress anyone. Consider ideas from this list for each slide.

Before Starting

Pick a bold, content-informed color palette: The palette should feel designed for THIS topic. If swapping your colors into a completely different presentation would still "work," you haven't made specific enough choices.
Dominance over equality: One color should dominate (60-70% visual weight), with 1-2 supporting tones and one sharp accent. Never give all colors equal weight.
Dark/light contrast: Dark backgrounds for title + conclusion slides, light for content ("sandwich" structure). Or commit to dark throughout for a premium feel.
Commit to a visual motif: Pick ONE distinctive element and repeat it — rounded image frames, icons in colored circles, thick single-side borders. Carry it across every slide.

Color Palettes

Choose colors that match your topic — don't default to generic blue. Use these palettes as inspiration:

Theme	Primary	Secondary	Accent
Midnight Executive	1E2761 (navy)	CADCFC (ice blue)	FFFFFF (white)
Forest & Moss	2C5F2D (forest)	97BC62 (moss)	F5F5F5 (cream)
Coral Energy	F96167 (coral)	F9E795 (gold)	2F3C7E (navy)
Warm Terracotta	B85042 (terracotta)	E7E8D1 (sand)	A7BEAE (sage)
Ocean Gradient	065A82 (deep blue)	1C7293 (teal)	21295C (midnight)
Charcoal Minimal	36454F (charcoal)	F2F2F2 (off-white)	212121 (black)
Teal Trust	028090 (teal)	00A896 (seafoam)	02C39A (mint)
Berry & Cream	6D2E46 (berry)	A26769 (dusty rose)	ECE2D0 (cream)
Sage Calm	84B59F (sage)	69A297 (eucalyptus)	50808E (slate)
Cherry Bold	990011 (cherry)	FCF6F5 (off-white)	2F3C7E (navy)

For Each Slide

Every slide needs a visual element — image, chart, icon, or shape. Text-only slides are forgettable.

Layout options:

Two-column (text left, illustration on right)
Icon + text rows (icon in colored circle, bold header, description below)
2x2 or 2x3 grid (image on one side, grid of content blocks on other)
Half-bleed image (full left or right side) with content overlay

Data display:

Large stat callouts (big numbers 60-72pt with small labels below)
Comparison columns (before/after, pros/cons, side-by-side options)
Timeline or process flow (numbered steps, arrows)

Visual polish:

Icons in small colored circles next to section headers
Italic accent text for key stats or taglines

Typography

Choose an interesting font pairing — don't default to Arial. Pick a header font with personality and pair it with a clean body font.

Header Font	Body Font
Georgia	Calibri
Arial Black	Arial
Calibri	Calibri Light
Cambria	Calibri
Trebuchet MS	Calibri
Impact	Arial
Palatino	Garamond
Consolas	Calibri

Element	Size
Slide title	36-44pt bold
Section header	20-24pt bold
Body text	14-16pt
Captions	10-12pt muted

Spacing

0.5" minimum margins
0.3-0.5" between content blocks
Leave breathing room—don't fill every inch

Avoid (Common Mistakes)

Don't repeat the same layout — vary columns, cards, and callouts across slides
Don't center body text — left-align paragraphs and lists; center only titles
Don't skimp on size contrast — titles need 36pt+ to stand out from 14-16pt body
Don't default to blue — pick colors that reflect the specific topic
Don't mix spacing randomly — choose 0.3" or 0.5" gaps and use consistently
Don't style one slide and leave the rest plain — commit fully or keep it simple throughout
Don't create text-only slides — add images, icons, charts, or visual elements; avoid plain title + bullets
Don't forget text box padding — when aligning lines or shapes with text edges, set margin: 0 on the text box or offset the shape to account for padding
Don't use low-contrast elements — icons AND text need strong contrast against the background
NEVER use accent lines under titles — these are a hallmark of AI-generated slides; use whitespace or background color instead

QA (Required)

Assume there are problems. Your job is to find them.

Your first render is almost never correct. Approach QA as a bug hunt, not a confirmation step. If you found zero issues on first inspection, you weren't looking hard enough.

Content QA

bash

python -m markitdown output.pptx

Check for missing content, typos, wrong order.

When using templates, check for leftover placeholder text:

bash

python -m markitdown output.pptx

Visual QA

bash

python scripts/thumbnail.py output.pptx

Check for:

Consistent spacing and alignment
Color contrast issues
Font consistency
Layout variety across slides
Missing images or broken elements
