About the palette

Ember is a sales-floor theme: a charred brown page #140B08, cards #1F120D and an ember orange #FF5F1F lead, with lemon #F3E81B, azure #52AFF6 and raspberry #F43363 next. Franklin Gothic Medium headings give leaderboards a scoreboard feel.

Use it for quota attainment and regional sales screens. The neutral grey #B8B8B8 series is useful for "rest of team" behind the highlighted reps. Status colours: good #7BD389, neutral #F8CF83, bad #FF4F5E. Text #FBEFE8 is 16.1:1.

Palette profile

Computed from the colours on this page, not written by hand: hue spread, lightness range, contrast and a colour-vision simulation of the first six chart colours.

Best for

Clustered and stacked charts with up to six series (6 hue families); add data labels to the pairs listed below.
Wall displays and dark-mode screens: text at 16.1:1 and every chart colour at 4.7:1 or more on the cards.
Variance charts, waterfalls and KPI deltas: good #7BD389 and bad #FF4F5E are 135° apart in hue.

Colour-vision simulation

Tritanopia: series 1 and 4 (#FF5F1F, #F43363); series 5 and 6 (#ADCD31, #B8B8B8)
Give those series data labels or direct labels instead of relying on the legend.

Chart colours: 8, in 6 hue families
Lightness range: 38–72 %
Text contrast: 16.1:1
Muted text: 8.2:1
Weakest chart colour: 4.7:1 on cards
Near-grey series: 1

Colours and contrast

Need a chart Power BI doesn’t ship?

Theme colours apply to custom visuals too. Describe the chart in plain English and VizForge generates it as a .pbiviz with its TypeScript source; in the design studio, the brief for a visual slot carries this palette. See the visual catalog.

Questions about this theme

Is the Ember theme accessible?

Yes. Text and muted text meet WCAG AA (4.5:1) on both the page and card colours, and every data and status colour reaches at least 3:1 against the cards. In a colour-vision simulation 2 pairs among the first six chart colours look alike; the palette profile lists them so you can add data labels. The full contrast table is on this page.

Which fonts does the Ember theme use?

It uses Franklin Gothic Medium for headings and Segoe UI for body text. All of them are in Power BI's own font list, so the report renders the same in Power BI Desktop and in the Power BI service.

How do I import a theme JSON into Power BI?

In Power BI Desktop go to the Design ribbon → Import theme and select the downloaded .json file; in the Power BI service use View → Theme pane (older Desktop builds: View → Themes → Browse for themes). The data colours, text classes and visual defaults apply to every page of the report.

Which theme JSON schema do these themes use?

They are compiled against the current report theme schema (reportThemeSchema-2.159) and include name, dataColors, background, foreground, tableAccent, good/neutral/bad, textClasses and visualStyles.
