Dark mode and custom colour themes for HubSpot
WHAT'S IN THE BOX
A purpose-built dark theme that keeps the UI readable while dropping the brightness - tuned for late-night sessions and low-light environments.
Read the launch post → CUSTOM THEMESAdjust background, text, accent, and border colours - or start from one of the preset palettes.
Read the docs → INSTANT SWITCHINGToggle between themes from the extension popup. Changes apply across every HubSpot page in the same browser session.
Why HubSpot needs dark mode →WHY A THEME EXTENSION
HubSpot only ships one visual theme - bright, white-heavy, and unchangeable. For anyone working long hours in HubSpot it's the kind of decision you don't notice you're paying for until your eyes start watering at 9pm. Theme Changer fixes the appearance layer without touching anything in HubSpot itself.
DARK MODE + CUSTOM THEMES
Theme Changer ships a tuned dark theme that keeps every HubSpot screen readable - workflows, contact records, dashboards, settings - and adds a custom-themes panel so you can roll your own palette by adjusting background, text, accent, and border colours. Switch between dark, light, and custom themes from the extension popup with one click.
LOCAL AND PERSISTENT
Theme Changer modifies HubSpot's appearance in your browser only. Your selected theme is saved locally and re-applied automatically next time you load HubSpot - and because nothing changes on the HubSpot side, every other user in your portal keeps their own preferred look. No admin involvement, no settings to roll out, no risk of breaking somebody else's view.
