About the palette

Chalkboard puts chalk yellow #F2DC6B on a slate-green page #142019, with peach #E8B4A0 and coral #F08A5D next and pale sky #9EC2E5 later in the list. It's a classroom look for attendance, attainment and training-completion pages shown in staff rooms.

Candara headings soften it for school audiences. Text #EEF3EC reaches 13.3:1 on the cards (#1B2A21). The accent doubles as the neutral status colour, so use the green good #9EE09E and coral bad #F08A80 for targets, and treat yellow as "this year".

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 13.3:1 and every chart colour at 6:1 or more on the cards.
Variance charts, waterfalls and KPI deltas: good #9EE09E and bad #F08A80 are 115° apart in hue.

Colour-vision simulation

Protanopia: series 1 and 4 (#F2DC6B, #B8E186); series 5 and 6 (#E5A3D6, #9BB7FF)
Deuteranopia: series 1 and 4 (#F2DC6B, #B8E186)
Tritanopia: series 2 and 5 (#E8B4A0, #E5A3D6)
Give those series data labels or direct labels instead of relying on the legend.

Questions about this theme

Is the Chalkboard 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 4 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 Chalkboard theme use?

It uses Candara 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.
