Why extract palettes from images?
Palette extraction is one of those tasks where having a starting point beats staring at a blank canvas. Brand work pulls palettes from photography in the same world as the brand. Motion designers extract palettes from a reference still to keep colors consistent across scenes. Web designers grab the dominant colors of a hero photo to drive a corresponding accent color throughout the site. Even casual social-media work benefits: pull a palette from your best three photos and the resulting feed feels cohesive without anyone consciously noticing why.
What the tool gives you
For each color in the palette you get the hex code (e.g. #3A4F66) and the RGB triplet (e.g. rgb(58, 79, 102)). Click any color swatch to copy its hex; use the "Copy all hex" or "Copy as rgb()" buttons to take the whole palette at once.
The colors are sorted by frequency in the image, so the first swatch is the most dominant. The order is useful for picking a primary, secondary, and accent triad in branding: take the first color as primary, the most contrasting later color as accent, and a mid-frequency desaturated color as supporting.
How the algorithm works
Median-cut quantization, in three steps:
- Sample the image down to a 200-pixel-wide thumbnail. This is enough to get a representative color distribution without crunching millions of pixels.
- Recursively split the pixel set along the color channel (R, G, or B) with the widest range. After N splits you have N boxes, each containing pixels that are close to each other in color space.
- For each box, compute the average color of all the pixels inside it. That average becomes the palette color. Sort the boxes by pixel count so the most frequent colors appear first.
This is deterministic and fast — a 4K image extracts in well under a second on a typical laptop. Transparent pixels in the source are excluded from the color set, so the palette reflects the visible content of the image rather than the background.
Using palettes in design and motion-graphics work
- Brand guidelines: a 5-color palette pulled from the founder's favorite photograph beats a "let's pick blue" branding session.
- Web hero design: extract the palette from your hero photo, use the most saturated mid-tone as your CTA button color — the page feels color-coordinated without effort.
- Motion graphics: if you're cutting a video that intercuts B-roll with talking head, pull palettes from both and find common tones — use those as your graphic accent colors so the cuts feel less jarring.
- Editorial design: pull a palette from the lead photograph of an article; use it for pull-quote backgrounds, callouts, and section dividers. The article feels visually unified.
