About the palette

Foundry Steel pairs a molten orange #F58F4C with a neutral steel page #121314 and cards #1C1E20. Mint #7DD3B0 and lime #8AC24F come next, then coral #E15D59, a split that works for good parts, rework and scrap on a shop-floor screen.

The neutral background keeps it from looking tinted under factory lighting. Status colours: good #8CD867, neutral #F6EE57, bad #F87288. Bahnschrift headings keep machine IDs and shift codes compact. Text #EDEDED is 14.2:1 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 14.2:1 and every chart colour at 4.7:1 or more on the cards.
Variance charts, waterfalls and KPI deltas: good #8CD867 and bad #F87288 are 110° apart in hue.

Colour-vision simulation

Deuteranopia: series 1 and 3 (#F58F4C, #8AC24F)
Give those series data labels or direct labels instead of relying on the legend.

Chart colours: 8, in 8 hue families
Lightness range: 54–83 %
Text contrast: 14.2:1
Muted text: 7.3:1
Weakest chart colour: 4.7:1 on cards
Near-grey series: 0
Closest catalog palettes: Copper Industrial (0.052)Desert Dusk (0.059)Night Market (0.060)

Colours and contrast

Contrast ratios are measured against the card (surface) colour, where visuals sit. Text needs 4.5:1; graphics need 3:1.

Questions about this theme

Is the Foundry Steel 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 1 pair 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 Foundry Steel 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.
