Sample the pixel you actually click
The tool maps the click position on the scaled preview back to the original image dimensions, reads that single canvas pixel, and reports its red, green and blue channel values. HEX is the same RGB triplet written as three two-digit hexadecimal values—for example, rgb(255, 0, 0) becomes #FF0000.
Why adjacent pixels can disagree
Edges, small text and shadows are commonly anti-aliased, so the browser blends foreground and background colors across several pixels. JPG compression can add further color variation around sharp edges. Zooming the page does not create a regional average: each click still selects one source pixel.
What the value does not tell you
The picker reports decoded RGB values, not a named paint color, print CMYK recipe, ICC profile analysis or accessibility contrast score. Transparent pixels also have an alpha channel, but the current result displays only RGB and HEX, so transparency is not reported separately.
A practical sampling workflow
- Upload an image and click the middle of a flat color area.
- Sample two or three nearby pixels to see whether compression or gradients are present.
- Copy the HEX or RGB value and test it in the destination design.
Processing stays in the browser. If the file cannot be decoded, use Image Converter first. Use Image Filters when the goal is to change rather than inspect color.
