Frequently Asked Questions

What is a Power BI theme JSON file?

A Power BI theme is a JSON file that defines colors, fonts, and visual styles applied consistently across all visuals in your report. It replaces the default Power BI color palette with your custom branding.

Is this Power BI theme generator really free?

Yes — 100% free with no sign-up, no watermark, and no limits. Download as many themes as you need.

What does WCAG contrast checking mean?

WCAG defines minimum contrast ratios for readable text. AA requires 4.5:1 for normal text; AAA requires 7:1. Our tool checks your text and background colors against these standards live.
