# Update theme

> Edit an existing theme's colours, fonts, or styling tokens.

Editing a theme changes its visual tokens. Project data isn't affected — only the look and feel of projects that use the theme.

<Steps>
  <Step title="Open the project's Themes panel">
    In the project editor sidebar, open the **Themes** panel.
  </Step>

  <Step title="Open the theme editor">
    Hover the theme row and click **Edit**.
  </Step>

  <Step title="Change the tokens">
    Update any of: name, **Primary colour**, **Palette mode** and individual chart colours, canvas colours, **Headings**, **Header background**, **Radius**, **Shadow**, and **Font**. You can also edit the cover-page and thank-you-page designs.
  </Step>

  <Step title="Preview">
    The project canvas previews your changes live as you edit.
  </Step>

  <Step title="Choose where it applies and save">
    Set **Apply to** (Current project, This client's projects, or All projects), then click **Save and apply**.
  </Step>
</Steps>

<Tip>
  If you change the **Primary colour** without overriding the chart palette, Oviond re-derives the ten chart colours from the new primary. Open **Edit chart colours** and set them by hand if you need specific colours pinned.
</Tip>

<Note>
  **Headings** colours heading widgets independently of body text. Leave it unset and headings follow the general **Text** colour.
</Note>

<Note>
  To make a copy instead of changing the original, hover the theme row and choose **Duplicate**. Editing themes requires permission to manage shared assets.
