    About this task

    When you edit Next Experience styles, you work in raw JSON code. Edit with care.

    You upload new typefaces or images in a separate process. See Add Next Experience font and image assets.

    Procedure

    1. In the filter navigator field, enter sys_ux_style.do to create a style record.
    2. Name the style and specify whether it’s a Core style or a Variant.
      Note:
      The Dark theme is the only variant shipped with Next Experience.
    3. In the Style field, add the base and properties blocks to contain overrides in the style record.
      {
        "base": {
      },
        "properties":{
        }
       }
      
    4. Optional: To save your work between steps, select the additional actions icon and choose Save.
    5. In the Style field, edit the JSON code to reflect the overrides you want the style to contain.
      1. Add or edit your main colors in the base section of the JSON code.
        Use RGB values.

        The following example shows sample color overrides.
