Pick a color
- Press ⇧⌘1 or choose menu bar › Screenshot › Pick Color.
- Move the pointer. The magnifier follows it, and the pill below shows the color code of the pixel in the center.
- Click (or press C) to copy the color code. A small alert on the notch confirms the color was copied, and the color also goes into your clipboard history.
