This iconpack looks very clean and has a light design, which is easy comparable with the sky. Most of the icons do have the sky-blue color and it should have a fresh look!
It's your choise, if you want to use a
light theme then you can use it without any problems. There's also
no problem if you want to take a
dark theme, it may look better too but it's your choise so it should be on your own.
