Open AIKIZI Color Palette on desktop, choose From Image, and add a JPG, PNG, or WebP. The tool extracts five color clusters locally in your browser; then you can lock, adjust, copy, and export the palette.

A palette extractor answers a deceptively simple question: which colors occupy this image? A useful palette workflow goes further. It asks which color is the field, which supports the subject, which creates contrast, and which tiny accent makes the image memorable.

How image color extraction works

AIKIZI’s image mode samples pixels and groups similar colors into five clusters using a lightweight k-means process in your browser. Each cluster is represented by a central color. Because the image is processed locally, it is not uploaded just to calculate the palette.

Clustering favors colors that occupy meaningful pixel area. That makes it good at finding the dominant visual environment, but a tiny important accent can be underrepresented. Always compare the extracted swatches with what your eye considers structurally important.

Privacy by design

In From Image mode, browser image APIs and a local canvas perform the extraction. Your image remains on your device during this palette calculation.

Go beyond HEX: assign every swatch a role

#111725
#174CA8
#2F82EF
#8E9AAA
#FF8C67
RoleWhat it doesTypical use
AnchorProvides the darkest structure and visual stabilityText, silhouette, deep background
DominantEstablishes identity and occupies the largest active areaPrimary surface, illustration field
SupportBuilds range without competing with the dominantSecondary elements, gradients, borders
NeutralCreates breathing room and makes chroma legibleBackground, typography field, interface chrome
AccentDirects attention with small, high-impact contrastCTA, focal glow, status, highlight

These roles matter more than the exact five codes. A successful palette can tolerate small HEX changes if its hierarchy remains intact. The same colors used in equal amounts may lose the entire mood.

A practical palette workflow

01

Extract on desktop

Use the From Image mode. The Lab currently recommends a desktop-sized screen for the full interaction.

02

Lock the non-negotiables

Lock the dominant and accent colors that define the image. Generate or adjust the remaining swatches around them.

03

Test a harmony

Try complementary, analogous, triadic, tetradic, or split-complementary relationships. Harmony is a starting structure, not a requirement to use every hue equally.

04

Test real UI roles

Place text on the background, a button beside the dominant, and the accent in a small area. A palette that looks beautiful as swatches can still fail in use.

05

Export in the format you need

Copy individual HEX values or export CSS variables, Tailwind colors, JSON, or a simple HEX list. Name colors by function—background, surface, primary, accent—not by arbitrary shade.

Example CSS roles

:root {
  --color-bg: #8E9AAA;
  --color-ink: #111725;
  --color-primary: #174CA8;
  --color-secondary: #2F82EF;
  --color-accent: #FF8C67;
}

What HEX codes cannot tell you

A flat color sample does not describe gloss, translucency, illumination, surrounding contrast, or area. Coral seen as light inside a translucent flower behaves differently from coral paint on a wall. Color appearance also changes with neighboring hues and display conditions.

For interface work, verify text and control contrast rather than assuming a harmonious palette is accessible. Color Intelligence adds WCAG-oriented contrast checks, color-vision simulation, and harmony analysis. For expressive image work, Decode’s VISUAL and MOOD views add color signature and emotional context.

Best practice

Save three things together: the HEX values, the role of each color, and a screenshot showing their intended proportions. That small record is far more reusable than five unlabeled swatches.

Extract a palette in your browser

Start from an image, organize the colors by role, and export tokens ready for design or prompting.
