Dominant Color Extractor FAQ
Do I need to create an account?
No, you can use this tool immediately without signing up or logging in.
Is my data secure and private?
Yes, all processing happens directly in your browser, so no data is ever sent to our servers.
Does it work offline?
Once the page is loaded, the core logic works offline since it runs locally in your browser.
How accurate are the extracted colors?
The image is first downscaled to about 80px wide, then colors are grouped into 16-level buckets and averaged per bucket for fast, representative results.
Are transparent pixels counted?
No. Pixels whose opacity falls below 50 percent are skipped entirely so invisible areas do not skew the palette.
How is it different from similar tools?
Everything runs entirely in your browser as local JavaScript - there is no account step and nothing is uploaded.
What is the technical working principle?
It uses the Canvas API to read pixel data and applies a color quantization algorithm to group and identify the most frequent colors.

Web designers use it daily to extract a complete color palette from a single hero image to build a cohesive website theme.
