FAQ

Power BI themes, explained

What is a Power BI theme file?

A theme is a small JSON file that sets the colors, fonts, and default formatting for every visual in a report. Loading one restyles the whole report at once, so your dashboards match your brand without formatting each chart by hand.

Is this theme generator really free?

Yes — no signup, no watermark. The file you download is a standard Power BI theme you own and can reuse anywhere.

What are the data colors for?

Power BI cycles through the dataColors list when it draws series in charts. We put your brand and accent colors first, followed by a balanced supporting palette, so charts look intentional out of the box.

Want the whole report, not just the theme?

Instant PowerBI takes your data and returns a finished, branded report — this exact theme applied, fully modeled, ready to open in Power BI Desktop.
