Set the brand once

Brand cleanup should not be the last task before every meeting.

OPF lets a deck share a color scheme and font scheme. Content can refer to named colors such as primary instead of repeating a hex value. Change the shared design and those references follow it; explicit overrides stay intentional.

{
  "design": {
    "colorScheme": {
      "primary": "#8CC8FF"
    }
  },
  "slides": [
    {
      "title": [
        {
          "text": "Ready for review",
          "color": "primary"
        }
      ]
    }
  ]
}

The same design system also supports organization logos and shared headers and footers. A footer can use {{slide.number}} / {{deck.slideCount}} so numbering follows the deck.

Why it matters: reusable brand choices reduce repetitive formatting and make it easier for people and agents to create a coherent set of presentations.
