How to Change Folder Color on Mac Using Preview
Using the preview app, you can customize the color of any folder. This is a multi-step process that's complicated enough that you will probably have to refer to this guide the first couple times you do it, but it isn't difficult.
Right click or control+click on the folder you want to customize.
Select Get Info from the context menu.
Click the folder icon in the upper left of the folder info window so that it is highlighted.
Click Edit in the menu bar near the top left of the screen and select Copy from the drop down menu.
Locate and open the Preview app.
With Preview open, click File in the menu bar.
Select New from Clipboard.
Select the Markup tool (looks like the tip of a pencil).
Select the Adjust Color icon (looks like a prism with light shining through).
In the Adjust Color window, slide the tint slider from left to right until you find the color you want, then click the X in the upper left corner of the window to close it.
You can use the other sliders, like saturation, to fine tune the color of your folder. You can also use the image editing software of your choice if the options in the Preview app don't give you the color you want.
Select the colored folder, and press command+C to copy it.
Return to the Folder Info box from earlier. If you have closed it, get it back by right clicking the folder you are trying to customize.
Click the folder in the Folder Info box, and press command+V.
You can now close the Folder Info box, and your folder will have the new color. If you want, you can repeat this process to customize as many folders as you like.
Customizing Folders With Images and Icons
You can customize your folders with your own images and custom icons using this same basic process. Instead of pasting a copy of your original folder into Preview, you need to open a photo or icon with Preview, and copy it. You can then paste it into the Folder Info box just like you did in step 11 above. This will replace the original folder icon with a custom photo or any other icon you like.
Changing Folder Colors on Mac With Apps
If the process outlined above seems too complicated or time consuming, you will find apps like Folder Color in the app store that are designed to automate the process. Folder Color in particular allows you to change the color of a folder, add small icons and decorations to a folder, replace a folder with an image, or even quickly edit one of your images into the shape of a folder.
