FAQ
Palette Extractor FAQ
How are the dominant colors calculated?+
The tool downscales your image on a canvas, samples thousands of pixels, and runs k-means clustering (8 iterations over 5 centroids) to find the five most representative colors — the same family of technique used by professional palette tools.
What do the contrast badges mean?+
Each swatch shows its WCAG contrast ratio against pure black and pure white, plus a rating: AA (4.5+, great for text), AA-Lg (3.0+, fine for large text and graphics), or Low (decorative use only).
Can I use these colors for my Instagram theme?+
Absolutely — that is the main use case. Copy the HEX codes into your story text colors, highlight covers, and Canva templates to keep a consistent feed aesthetic.
Are my images uploaded anywhere?+
No. Pixel sampling and quantization run 100% locally via the Canvas API. Nothing ever leaves your browser.
