A theme sets the colors and corner radius of the SteelEngine interface. Themes come in three scopes, and every member picks one per organization.
Who can do what
| Built in | Organization | Yours | |
|---|---|---|---|
| Who sees them in the gallery | Everyone | Every member of that organization | Only you, in every organization |
| Who can create | Nobody | Organization admins | Any member |
| Who can edit or delete | Nobody | Organization admins | You |
| Where your selection lives | Per organization | Per organization | Per organization; the theme itself follows you |
| What happens on delete | n/a | Members who selected it move to its twin, or to System | Your selection in every organization moves to its twin, or to System |
| Limit | 2 | 20 per organization | 20 per person |
Open the gallery
The gallery lives at {{APP_URL}}/<your-org>/themes. You can reach it from:
- Organization Settings sidebar, under Appearance
- The theme menu in the workspace sidebar, then All themes
- Workspace Settings → General, then Open themes
The gallery has three sections.
| Section | What it holds |
|---|---|
| Built in | Light, Dark, and System, which follows your device between Light and Dark |
| Organization | Themes made by your organization's admins |
| Yours | Your personal themes |
Click a theme to select it. You can use one theme in one organization and a different theme in another.
Build a theme
Select New theme in the Organization or Yours section.
The editor opens with a Start from strip. Pick one starting point:
- Choose a logo: upload an image and the editor extracts its colors
- Company website: enter a domain and the editor reads the site's brand colors from its theme metadata, manifest, stylesheets and icons
- Seed color: pick one color and the editor derives the rest
- A built-in theme, to adjust from a known palette
Then choose a Base appearance, Light or Dark, and adjust the Radius and the color dials. The editor shows a contrast badge for each color role and a live preview. Name the theme and save it.
Website extraction is limited to 10 lookups per user per minute. If a site cannot be read, the editor tells you why and you can continue from a seed color instead.
Linked pairs
A theme is built on one base, Light or Dark. To give it a partner on the opposite base, open its menu in the gallery and select Add a dark version or Add a light version. The editor opens with the partner pre-filled from the original, and saving links the two as a pair.
A linked pair appears once in the gallery. Select Use both on the pair to follow your device appearance, the same way System does for the built-in themes, or select either half on its own.
Edit and delete
Open a theme from the gallery to edit it. Saving a theme never changes anyone's selection. Deleting one does, as the table above describes.
Themes and white-label branding
White-label colors apply only while a built-in theme is selected. A custom theme replaces them. The white-label logo and wordmark apply under every theme. See Enterprise for white-label setup.
