The color picker tool in Photoshop is a great way to select colors for your project. You can use it to select colors from an image, or from the color palette. To use the color picker tool, simply click on the color you want to select.
The color picker tool will then display the color code for that color. You can also use the color picker tool to change the color of an object in an image. To do this, simply click on the object you want to change the color of, and then click on the color you want to use in the color picker tool.
