Overview
Introduction
This tool finds a logo's dominant color scheme, entirely in your browser, ranking each color by how much of the visible mark it covers.
It's a fast way to document a logo's actual brand palette straight from the exported file.
What Is Logo Color Scheme Finder?
A logo-focused wrapper around the site's general PNG color palette extractor: it groups similar pixel colors into buckets, counts how many visible pixels fall into each, and returns the top N buckets as hex colors with usage percentages.
It's frequency-based color analysis, not a design-tool color-theory suggestion.
How Logo Color Scheme Finder Works
Every non-transparent pixel's RGB is reduced to 4 bits per channel (16 levels) and combined into a single bucket key, so slightly different anti-aliased shades of the same color count together.
Buckets are sorted by pixel count, the top N are converted back to representative hex colors, and each is reported with its raw pixel count and percentage of the visible image.
When To Use Logo Color Scheme Finder
Use it to reverse-engineer a logo's exact brand color palette when you only have the exported PNG, not the original design file.
It's also useful for auditing whether a logo export accidentally introduced extra, unintended colors.
Often used alongside Logo Color Picker, Logo Colors Changer and Logo to Single Color Converter.
Features
Advantages
- Runs entirely client-side; nothing is uploaded to a server.
- Bucketing merges near-duplicate anti-aliased shades into a clean, readable palette.
- Reports both raw pixel counts and percentages for each color.
Limitations
- 4-bit-per-channel bucketing can merge genuinely distinct but visually close colors into one entry.
- It's a statistical summary of pixel frequency, not a guarantee those are the 'official' brand hex values from the original design file.
Examples
Best Practices & Notes
Best Practices
- Request more colors (closer to 32) for logos with gradients or subtle shading, fewer for flat two- or three-color marks.
- Cross-check extracted hex values against official brand guidelines rather than treating them as authoritative.
Developer Notes
This lib function is a thin, validating wrapper around the already-shipped `extractPngColorPalette` from the general PNG category — the bucketing and frequency-counting logic is identical whether the source pixels are a logo or any other PNG.
Logo Color Scheme Finder Use Cases
- Reverse-engineering a logo's brand colors from an exported PNG
- Auditing a logo file for unintended extra colors
- Documenting a client's brand palette from an existing logo asset
Common Mistakes
- Requesting only 1-2 colors for a logo with a gradient, losing most of the color detail.
- Treating extracted hex values as pixel-perfect brand colors without cross-checking the source design file.
Tips
- Combine with the Logo Color Picker to verify one specific extracted color against an exact pixel sample.
- Use a higher color count first, then manually consolidate visually-similar entries if needed.
