How to Pick Colors From an Image
“What color is that?” is a deceptively deep question. A logo that reads as one solid blue is, at the pixel level, dozens of slightly different blues — and picking the wrong pixel gives you a brand color that's subtly, naggingly off.
How an eyedropper works
The image is drawn onto a canvas and the tool reads the exact red, green and blue values of the pixel you click, then expresses them as HEX (#3b82f6), RGB and HSL. Same color, three notations — HEX for CSS and design tools, HSL when you want to reason about lightness and saturation.
The traps that skew your pick
Anti-aliasing: edges are blended. Pixels where a logo meets its background are mixtures of both — click the flat interior of a shape, never its outline.
JPEG compression:lossy compression scatters near-identical values through “solid” areas and smears colors near edges. Pick from the middle of large flat regions, and prefer PNG sources for logos when you can get them.
Shadows and gradients:a photographed object carries lighting. The “true” color of a product in a photo is usually somewhere between its lit and shaded sides — pick several points and compare.
Scaling blur: heavily downscaled images blend neighboring pixels. For fine detail, pick from the original-size image.
From one color to a scheme
Good palettes usually come from images: photograph a sunset, pick four points, and you've got a scheme nature already color-graded for you. The workflow that works: pick 3–5 candidate colors from the image, feed the main one into a palette generator for tints/shades and harmonies, then verify text-on-background pairs meet WCAG contrast before shipping.
Matching brand colors
When the style guide is missing (always), the logo is the source of truth. Pick from a flat area of the official logo file — ideally the SVG or PNG from the brand's own site, not a re-compressed social media avatar. If several picks disagree by a hair, round to the “cleanest” value; brands overwhelmingly use round-ish HEX values.
Pick privately
The image color picker shows a live color under the cursor, saves up to 12 clicked swatches with HEX/RGB/HSL and copy buttons, and never uploads the image — safe for unreleased designs. Continue with the palette generator to build the scheme and the contrast checker to keep it accessible.
