A variety of Mac apps have the built in colour selector. For example, if you want to change the colour of text within TextEdit, the shape colour within Preview. Practically anything in any app that uses the colour selector. This post is going to show you how to pick the exact colour of something on the screen. For example, if you have a blue hue that you want to use within a document, you can see it on your screen, we can pick this colour easily. It is far quicker than using the sliders or the colour wheel.
Picking The Exact Colour
Within the colour picker there are a variety of different tools used to select a colour. For example the colour wheel, the sliders and various different spectrum’s.
To select the exact colour you want, click on the little magnifying glass near the top of the app. This will select a colour picker. You can now use the magnifying glass to however over the colour you want. When you click with the mouse, that colour will be selected.
The little magnifying glass, as the name suggests, also zooms in and magnifies every so slightly. This way you can pick the exact pixel you want, thus the exact colour. When you have selected the colour it will pop into the colour picker window. This colour can then be used to colour anything.
This is only a simple trick, but it is one I only recently found. Its very useful if you want to match a colour and don’t know how to select it within the colour picker.
