How this tool works

What it does

Computes the mean colour of a whole-image canvas sample and reports HEX/RGB/HSL/HSV/CMYK.

Transparency

Choose to ignore, alpha-weight, or include transparent pixels; the mode is shown in the result details.

Colour space

Values come from the browser-rendered sRGB canvas, not the raw file bytes.

Privacy

Everything runs in your browser on a canvas — your image is never uploaded.

Average Color Finder in your browser

Average Color Finder reads the sampled pixels of your image on a browser canvas and reports the mean colour as HEX, RGB, HSL, HSV and CMYK. It samples the whole image with its full aspect ratio preserved — it does not crop a square out of the centre — and the result panel shows exactly how many pixels were sampled.

Because transparent areas can skew an average, you choose how alpha is handled: ignore transparent pixels (the default), weight each pixel by its alpha, or include every pixel as opaque. A minimum-alpha threshold drops near-transparent edges.

Colours come from the browser-rendered sRGB canvas, not the raw file bytes, so embedded colour profiles, CMYK source data or HDR may shift the values slightly. Copy any value with one click, or download the result as TXT, JSON, CSS variables or CSV.

How to use Average Color Finder

  1. Upload an image to Average Color Finder — click the drop zone, press Enter, or drag a file in.
  2. Choose how transparent pixels are treated (ignore, alpha-weighted, or include all) and set the minimum-alpha threshold.
  3. Pick the download format (TXT, JSON, CSS variables, or CSV), then click Process to compute the average.
  4. Copy the HEX, RGB or HSL value, or download the colour-data file.

Why use Average Color Finder

Whole-image sample

Averages a full-coverage sample with the aspect ratio kept — no centre-crop that discards the edges.

Alpha-aware

Ignore, alpha-weight, or include transparent pixels so PNG/WebP cut-outs don't skew the result.

Developer formats

HEX, RGB, HSL, HSV and CMYK on screen; TXT, JSON, CSS variables and CSV to download.

Private & local

The image is read on a canvas in your browser and never uploaded.

Design QA

Check the overall colour cast of a render or export at a glance.

CSS variables

Drop the averaged colour straight into a stylesheet as a custom property.

Frequently asked questions

Does Average Color Finder average every pixel or a sample?

It samples the whole image with the aspect ratio preserved (no centre-crop) and downscales large images for speed; the result panel shows the exact sampled size in pixels. For most photos a full-coverage sample is visually identical to averaging every pixel.

How does Average Color Finder handle transparent pixels?

You choose: ignore fully or near-transparent pixels (the default), weight each pixel by its alpha, or include every pixel as opaque. The result panel records which mode was used and how many pixels were skipped.

Which colour formats does Average Color Finder output?

HEX, RGB, HSL, HSV and CMYK are shown on the page, and you can download TXT, JSON, CSS variables, or CSV. CMYK is an approximate sRGB-to-CMYK conversion, not a print-accurate profile.

Do colour profiles affect the average?

Possibly. Values are read from the browser-rendered sRGB canvas, not the raw file bytes, so embedded ICC profiles, CMYK source data, HDR or browser colour management can shift the numbers from a colour-managed application.

Is my image uploaded to compute the average?

No. The image is decoded and sampled by browser canvas APIs on this page; no image file is sent to a server.
