In the last version of Coolors, we introduced the possibility to save your favorite colors.
To add a color to the favorites just click on any HEX value in the Generator to open the Color Inspector. Then go to the Sets tab and to Favorites.
Click on the three dots icon to open the menu and select Add color.
Choose a name and the color you want to save and you're done!
Your colors will be available here. So every time you need to create a new palette you can start from your most loved tints.
