ColorSlurp's magnifier lets you pick colors from anywhere on your screen.

Picking colors

To pick a color, click the dropper button at the top of ColorSlurp's window. Move the magnifier with your mouse until you find your desired color, then click to select it.

You can also set a global shortcut to show the magnifier. See the shortcuts page for more info.

Choosing a different format to copy to

By default, the magnifier copies the selected color to your default color format. However, if you need to copy it to a different format, hold while picking the color, or right-click instead of left-clicking. This will show all the available copy formats.

Picking Multiple Colors at Once

Hold control when picking a color to add it to the magnifier's palette. You can add as many colors as you'd like as long as you continue to hold control. When you're ready to save the palette press return or click without holding control. You'll be given the option to save the colors to an existing palette or create a new one.

TIP! You can undo/redo picking multiple colors by using the shortcut ⌘Z or ⇧⌘Z

Precision mode

Precision mode slows down the speed of the magnifier, making color selection more precise. This is especially useful if your mouse speed is fairly fast.

To enable precision mode, long press with your mouse (click and hold). You can also hold shift while picking colors too!

Changing the size and zoom

Change the size of the magnifier by scrolling up and down, or by using the plus and minus keys on your keyboard.

Change the zoom of the magnifier by holding option while scrolling, or using the [ and ] keys on your keyboard.

Other customization

The displayed value in the magnifier can be changed, along with many other settings in ColorSlurp's preferences.

You can also change the shape of the magnifier from the default square to a circle.

Enabling screen recording

In order for the magnifier to zoom and pick colors, ColorSlurp requires permission to access your screen.

The magnifier only takes a small 32x32 pixel screenshot in the center of where the magnifier is located, then zooms and displays the image. This only happens when the magnifier is visible and the mouse is moved. The image is never saved and ColorSlurp does not store any screen recording data. If you change your mind, you can always revoke access in System Settings.

To allow screen recording, go to:

System Preferences > Security & Privacy > Privacy > Screen Recording

Then click the checkbox for ColorSlurp. After doing that you must quit and relaunch ColorSlurp for the change to take effect.

Trouble Shooting Screen Recording

If ColorSlurp continues to ask for screen recording if you enabled it, try the below steps. Sometimes the screen recording settings on Mac can sometimes be buggy, however usually completely removing an app from the screen recording settings, then adding it back will fix it:

  • Quit ColorSlurp
  • Open the screen recording system settings page (found under privacy and security).
  • Click on ColorSlurp in the list, then click the minus button to remove it.
  • Click on the plus button, then find and select the ColorSlurp application. Since it looks like you’re using the beta version of ColorSlurp, make sure to choose that version of the app.
  • You should be able to relaunch ColorSlurp and it should work properly.
