The ShareX screen color picker samples the pixel under your mouse pointer and copies its color value to the clipboard. It works across the full virtual desktop, including multiple monitors, and includes a magnified preview for selecting small UI details accurately.
Open it from Tools -> Screen color picker. You can also open it with the eyedropper button in the color picker.
Right-click or press Esc to cancel without copying anything. Hold Ctrl while selecting to use the alternate clipboard format.
By default, a normal click copies the hexadecimal value and Ctrl + click copies the RGB channels. A notification confirms the text placed on the clipboard when task-completion notifications are enabled.
Open Task settings -> Tools to change:
The format fields support ShareX pixel-information tokens. Common examples include $HEX for an uppercase hexadecimal color, $r255, $g255 and $b255 for decimal RGB channels, and position tokens for the selected screen coordinate. You can combine tokens with your own punctuation or labels to produce values such as CSS colors, comma-separated RGB values or diagnostic text.
