A little known feature of his Mac is that your operating system comes with a meter that can identify RGB and hexadecimal color of a screen pixel or rather your Wallpaper you have on your desktop, and in this tutorial we are going to show you how it is done.
Identify the RGB value of any pixel on your Mac screen.
Whether you are trying to modify a photograph, and you need to change the tone of a color either in Adobe Photoshop o Pixelmator, or you're trying to make a nifty little graphic, knowing the RGB values of a pixel in an existing environment can be very helpful in getting the color effects you're looking for.
Your Mac comes equipped with a utility called 'Digital Color Meter', and can be found in Launchpad> Others through the dock (how you can see in the image above).
After starting the application, you can drag the pointer anywhere you want on the screen, and it will show an enlarged view of the area in which it is pointing, and it emphasizes that it is exactly what you are measuring, where you can also choose multiple formats as a native, P3, sRGB, Generic RGB, Adobe RGB, yy L * a * b *.
In this example, I am measuring the color RGB of a part of the Wallpaper mountain that comes by default on the desktop of the OS X El Capitan.
As you can see, the values come to be a red of 88, a green of 33, and a blue of 40. You could use these same values in an application like Adobe Photoshop o Pixelmator to generate the same colors to use for image editing.

The RGB display is the tip of the iceberg with the 'Digital Color Meter' on your Mac. It can also be used to access hexadecimal color values, which are useful for web designers What do they use CSS y HTML regularly. As a graphic designer and developer, for me it is essential, where I usually use extensions in browsers to make this tedious task easier for me.
To change from values Standard decimal RGB to hexadecimal values, you have to click on the tool 'Digital Color Meter' to change your menu to your own, and then click Display > You show values> With the hexadecimal system to change the values to this format.
