About Pigomentry

Pigomentry is a small set of color tools built to actually work — no accounts, no uploads, no waiting on a server.

What it does

Pigomentry runs seven tools entirely as client-side JavaScript in your browser: a color converter, a palette generator, a WCAG contrast checker, a gradient generator, an image color extractor, a color blindness simulator, and a color mixer. Alongside them are four reference guides covering the accessibility and color-space background behind the tools, each fact-checked and sourced rather than written from memory.

Why local-only matters

Every tool here processes your input — including any image you upload — using the browser's own Canvas and FileReader APIs. Nothing is sent to a server, because there's no server-side processing involved in any of these tools. That's not a privacy feature bolted on afterward; it's simply how color math and canvas pixel-reading work.

Accuracy

The conversion formulas, WCAG contrast math, and color-blindness simulation matrices used on this site are standard, published algorithms — not proprietary guesses. Where a page cites a statistic (contrast thresholds, color-blindness prevalence), the source and the date it was checked are listed at the bottom of that page.
