Do you have a loupe on your Mac? A loupe on the Mac is a small app which magnifies the pixels on the screen so you can capture color information.
If you’re into graphic design then I’m sure you have more than one loupe. It’s the nature of the business. If you’re not into graphics and pixels and colors, Apple includes a built-in loupe in OS X. Here’s a look at five ways to magnify your Mac’s screen and capture the color information on any visible pixel.
First on the list is the Digital Color Meter which is already on your Mac. Check in Applications > Utilities and double-click.
There’s not much to Apple’s loupe, but it works and it’s priced right.
If you don’t want to spend much money but need a few more features, start with Pickr. This one resides in the Mac’s Menubar and gives you options for different kinds of colors (Hex, RGB, NSColor, etc.).
The same money gets you Zoom It, which I keep installed on my Mac. Zoom It comes with keyboard shortcuts, multiple loop sizes and shapes, and can stay on the screen if needed.
A few dollars more gets you the creatively titled loupe called Loupe.
Loupe features a circle or square loupe with a customizable appearance. You can adjust the loupe size and the zoom level. As with most loupes Loupe resides in the Menubar but also has keyboard shortcuts to open.
At the high end of the loupe industry is xScope, which goes far beyond loupe with options to measure pixels between graphic elements, onscreen ruler, screen guides, screen frames, and crosshair. A mere pixel grabber xScope is not.
Those five are simply a small cross section of Mac screen and pixel grabbing tools.
