The immensely popular Advanced Custom Fields plugin is used by a lot of developers. One of many reasons for working in ACF is the user-friendly admin section.
One of the many modules is obviously the color picker. This module got so called swatches in 2014 which is a great way to easily access colors used on the website.
Color Picker looks like this and comes with a bunch of predefined colors.
So how do I set my own colors?
You can’t change the colors from admin.
