About the palette
Solar Field opens with sun amber #B7791F, then a teal #3E8E8A and leaf green #4E8A3E, mirroring how renewables reports usually split generation, storage and grid export. The page is a warm white #FBF8EF and Bahnschrift headings keep MWh and capacity-factor figures compact.
Rust #C04A2B is in the series for curtailment or losses, while the bad status colour #B3261E stays redder for alarms. Every series reaches 3:1 on the white cards, so thin line charts of daily irradiance remain visible. Text is #1F1A0E at 17.3:1.
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 (7 hue families); add data labels to the pairs listed below.
- Thin line charts and sparklines on white cards: every chart colour reaches 3.6:1 or more.
- Variance charts, waterfalls and KPI deltas: good #2E7D32 and bad #B3261E are 120° apart in hue.
Colour-vision simulation
- Protanopia: series 1 and 3 (#B7791F, #4E8A3E)
- Deuteranopia: series 3 and 4 (#4E8A3E, #C04A2B)
- Tritanopia: series 2 and 3 (#3E8E8A, #4E8A3E)
- Give those series data labels or direct labels instead of relying on the legend.

A Power BI combo visual titled "Daily generation vs expected". Purpose: Generation (columns) vs expected (line). It sits in a 784×208 px slot on a designed report page. Match the report's brand: data colours #B7791F, #3E8E8A, #4E8A3E, #C04A2B, #8B4F8F, #2B4C7E; background #FFFFFF; text #1F1A0E; font Segoe UI. Transparent visual background so the page design shows through; no visual border. The report uses the Solar Field Power BI theme.

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.

Is the Solar Field 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 3 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 Solar Field theme use?
It uses Bahnschrift 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.
