About the palette

Aurora Night is a soft dark theme: midnight-violet page #100F26, cards #191838, and an aurora lilac #B49CFF lead. Mint #7DE3C3, blush #FFB3C7 and ice blue #9CC9FF follow, light tints that glow without the harshness of neon.

It suits cloud-cost, forecast-accuracy and planning pages viewed on dark-mode laptops. Because the series are all light, fills look gentle; use the darker card colour for gaps between bars. Text #E8F6F7 reaches 15.4:1 on the cards.

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 (8 hue families); add data labels to the pairs listed below.
Wall displays and dark-mode screens: text at 15.4:1 and every chart colour at 7.4:1 or more on the cards.
Variance charts, waterfalls and KPI deltas: good #6CE4B5 and bad #F78C8C are 157° apart in hue.

Colour-vision simulation

Protanopia: series 2 and 6 (#7DE3C3, #FFCF9E)
Deuteranopia: series 2 and 3 (#7DE3C3, #FFB3C7); series 5 and 6 (#E6F59A, #FFCF9E)
Tritanopia: series 2 and 4 (#7DE3C3, #9CC9FF); series 3 and 6 (#FFB3C7, #FFCF9E)
Give those series data labels or direct labels instead of relying on the legend.

Questions about this theme

Is the Aurora Night 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 5 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 Aurora Night theme use?

It uses Segoe UI. 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.
