About the palette

Lab Bench opens with a lab cyan #0B7A9E, then violet #8E4FC2 and orange #E07A2E, colours far apart in hue and lightness, which suits batch, assay or trial-arm comparisons. The page #F3F8FB is a cool clinical white.

Use it for pharma quality, lab throughput and research-portfolio pages. The eight series end with green #3E8E4A and teal #2E8A8A for control groups. Text is #0E1C24 at 17.3:1 and muted text #4A5D68 is 6.8:1, enough for dense axis labels on scatter plots.

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 3:1 or more.
Variance charts, waterfalls and KPI deltas: good #2E7D4F and bad #B3261E are 142° apart in hue.

Colour-vision simulation

Protanopia: series 2 and 6 (#8E4FC2, #4A5AA8); series 3 and 4 (#E07A2E, #9A8A2E)
Deuteranopia: series 1 and 2 (#0B7A9E, #8E4FC2)
Give those series data labels or direct labels instead of relying on the legend.

Chart colours: 8, in 7 hue families
Lightness range: 33–54 %
Text contrast: 16.2:1
Muted text: 6.4:1
Weakest chart colour: 3:1 on cards
Near-grey series: 0

Questions about this theme

Is the Lab Bench 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 Lab Bench 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.
