The EyeDropper.open() method starts the eyedropper mode, returning a promise which is fulfilled once the user has selected a color and exited the eyedropper mode.

options Optional

An options object to pass an AbortSignal signal:

signal

An AbortSignal. The eyedropper mode will be aborted when the AbortSignal's abort() method is called.

A Promise that eventually resolves when the user selects a pixel color from the screen.

The promise resolves to an object with the following property:

sRGBHex

A string representing the selected color, in hexadecimal sRGB format (#aabbcc).

Exceptions are not thrown but returned when the Promise is rejected. The promise is rejected in two cases:

• When the user dismisses the eyedropper mode by pressing the Escape key.
• When the eyedropper mode is aborted by the AbortController passed as an argument to open().

• The EyeDropper interface it belongs to.
