Serenity

“Serenity icons are an ongoing project where the alternatives are the real stars of the app. No one says an app has to have a specific icon. Try switching out that boring phone icon with your favorite superhero character!! It’s easier than ever with this well-organized dashboard, including search support. These are completely flat icons with a soft and gorgeous fixed color palette.”
