In-Browser Statistical Color Distribution and Vibrancy Analysis
The Image Color Analyzer provides statistical pixel analysis and hue distribution profiling for digital images. Visual designers, digital marketers, and brand managers require objective metrics regarding color composition, warmth, saturation levels, and tonal distribution. This utility samples raw canvas ImageData to categorize pixels into canonical hue buckets, compute Hasler-Süsstrunk vibrancy metrics, evaluate color temperature, and plot 16-bin luminance histograms.
All image sampling and statistical calculations take place strictly on the client side using browser HTML5 Canvas APIs. Raw image pixels are processed in local memory without uploading files to remote servers or external cloud storage.
Core Tool Capabilities
- Hue Bucket Categorization: Group pixels into nine canonical color categories, including Red, Orange, Yellow, Green, Cyan, Blue, Purple, Magenta, and Neutral/Monochrome.
- Hasler-Süsstrunk Vibrancy Rating: Calculate colorfulness scores on a 0 to 100 scale to quantify color saturation and variance across sampled pixel matrices.
- Color Temperature Profiling: Determine warm versus cool color distribution ratios and classify overall image temperature ratings.
- 16-Bin Luminance Histogram: Visualize tonal distribution across 16 luminance bins from deep shadow tones to pure highlight levels.
- Structured Report Exporting: Copy complete analysis outputs as structured JSON or download spreadsheet CSV reports for design documentation and compliance audits.

Frequently Asked Questions
- Are my uploaded images sent to any server for color analysis?
- No. All pixel sampling, color bucket sorting, and statistical calculations are performed entirely in your browser memory using HTML5 Canvas APIs.
- What formula is used to calculate the Vibrancy Score?
- The Vibrancy Score uses an adapted Hasler-Süsstrunk colorfulness algorithm that combines the standard deviation and trigonometric mean of red-green and yellow-blue color differences in CIELAB color space.
- How does the color temperature rating work?
- Color temperature measures the ratio of warm hue angles (red, orange, yellow) versus cool hue angles (cyan, blue, purple) to categorize overall image warmth.
- Can I download or copy the analysis results?
- Yes. You can copy the raw analysis data as formatted JSON or download a CSV report containing category coverage, pixel counts, and average saturation.
