# User interface customization

> Use this section to change how the Design Editor interface looks in your storefront.

- [UI themes](https://customerscanvas.com/docs/on-premises/design-editor/iframe-api/customization/ui-themes.md) — switch the interface theme; you can apply either **Aurum** or **MdLight**.
- [Primary color](https://customerscanvas.com/docs/on-premises/design-editor/iframe-api/customization/primary-color.md) — change the primary color without switching themes.
- [Preloader](https://customerscanvas.com/docs/on-premises/design-editor/iframe-api/customization/preloader.md) — replace the preloader shown while the editor loads.
- [Localization](https://customerscanvas.com/docs/on-premises/design-editor/iframe-api/customization/localization.md) — adapt the editor to another language. The Design Editor provides localization files for English (`en`), Spanish (`es`), French (`fr`), and Russian (`ru`).
- [Icons](https://customerscanvas.com/docs/on-premises/design-editor/iframe-api/customization/icons.md) — customize the icons shown in the editor.
