What does Image Color Picker do?
It lets you click anywhere on an uploaded image to sample the exact color at that pixel, shown as HEX, RGB, and HSL values.
How accurate is the sampled color?
It reads the actual pixel value from the Canvas API, so it's exact for the image as decoded by your browser — note that heavily compressed JPEGs can have slightly different pixel colors than the original scene due to compression artifacts.
Where is my image processed?
Locally in your browser; the image is never uploaded.
