Three ways to average an image: plain mean, square root for how light actually mixes, or most dominant.

What is Online Image Average Color Finder?

Image Average Color Finder is a free online tool for finding average color in an image by interpolating all colors in an image. You can use this color as background color, gradient, border, box shadow or for any other purpose. There are 3 different algorithms you can select for finding the average color of an image. These are listed below.

  • Simple: As the name suggests, it processes all color units one by one, accumulates all reds, greens, blues, and alphas, divides them by the number of units and makes a simple interpolation for finding image's average color.
  • Square Root: Only difference between simple and square root algorithm is square root algorithm takes square root of the accumulated colors.
  • Dominant: It tends to find not average but the most used and dominant color in an image.

Frequently asked questions

Why are there three algorithms?

Because "average" is ambiguous. Simple takes the plain mean of every pixel. Square root averages in a way that respects how light actually mixes, which usually looks more like what your eye expects. Dominant ignores the mean entirely and reports the colour that appears most.

Which one should I use?

Square root for a background tint that should feel like the photo. Dominant when you want the colour a viewer would name if asked what colour the picture is. Simple is mostly useful as a reference point.

Why does the simple average often look muddy?

Because averaging opposite colours lands you in grey-brown. A photo of a blue sea under an orange sunset has no meaningful midpoint — which is exactly when the dominant option is the better question to ask.

What can I do with the result?

Use it as a page background behind the image, as a placeholder colour while the image loads, or as a border or shadow that picks up the photo without competing with it.

Can I get every colour instead of one?

Yes — the Image Color Extractor builds a full palette from the image, and the Image Color Picker reads a single pixel you point at.
