Category leaderboard
Categories with n>=20 are shown as directional; below that, treat counts as absolute source[1].
| Category | Dark | Light | n | Lean |
|---|---|---|---|---|
| Entertainment | 38 | 4 | 42 | Dark 90% |
| Music | 19 | 5 | 24 | Dark 79% |
| News | 19 | 11 | 30 | Dark 63% |
| Health & Fitness | 39 | 32 | 71 | Even |
| Education | 25 | 23 | 48 | Even |
| Finance | 20 | 22 | 42 | Even |
| Lifestyle | 11 | 21 | 32 | Light 66% |
| Food & Drink | 7 | 33 | 40 | Light 83% |
Developer Tools (13/5, n=18) and Medical (2/17, n=19) are strong but sit just under the n>=20 directional bar source[1].
How to apply it
Media and content-immersion categories (Entertainment, Music, News) treat dark as the honest default — dark surfaces make cover art, video and album grids pop, and Netflix and Spotify anchor that convention source[2]. Consumption-and-trust categories (Food & Drink, Medical, Lifestyle) default light. If you are in a near-even category (Health & Fitness, Education, Finance), the theme choice is genuinely yours — lead with your platform convention instead.
Caveats
Per-category cuts below n=30 (Music, Developer Tools, Medical, Books, Photo & Video) are reported as absolute counts, not stable percentages source[1]. Travel (n=2) and Business (n=10) are too small to read at all.
