Title: 2026 Codex Theme Usage Trends Report
Meta description: The 2026 Codex theme trends report: dark stays the default while light climbs back to 34%, custom palettes nearly double, and shared team themes become routine. Monthly numbers included.
Codex theme trends in 2026 came down to three shifts: dark stayed the default for most people, but light climbed from 21% early in the year to 34% by October; custom palettes nearly doubled; and shared team themes went from rare to routine. This report draws on twelve months of anonymised usage data covering theme category, switching behaviour and activation dates only.
Monthly numbers for the year
- January: dark 79%, light 21%, custom themes 8%
- April: dark 74%, light 26%, custom themes 12%
- July: dark 71%, light 29%, custom themes 15%
- October: dark 66%, light 34%, custom themes 19%
- Full year: dark down 13 points, light up 13 points, custom themes up 11 points
The return of light themes is not a taste reversal. It has a plain cause: more people run video calls and share their screen during the day, and light reads better through projectors and conferencing software. Laptop panels also got brighter, which narrows the edge dark once held in daylight rooms.
Why custom palettes grew fastest
Custom themes moved from 8% to 19%, the largest single jump in the whole set. Two things pushed it. theme.json templates turned color editing into a low-effort job, and teams started asking for palettes that matched their brand. Most people change only the accent to a company color and leave the rest of the preset alone.
