Choose a language#

Use the language selector to switch between Portuguese, English and Spanish. Save your account language in Settings. Project language guides requests and content; changing the interface language does not automatically translate existing projects.

Light, dark or system#

Light mode is the default. Use the theme button to switch quickly, or choose Light, Dark or System in Settings. System follows your device preference. A saved choice is respected on subsequent visits in that browser.

Interface and project differ#

Changing Vellun’s theme changes the platform, not the published design of your project. To change a created site’s colors and appearance, request the edit in that project’s chat.
