How to repeat string and take parts of it in Haskell

I need to write a Haskell program that takes an integer and a list and repeats the characters of the list up to n digits:

Int -> [a] -> [a]

e.g. 3 "pink" would give "pin"
6 "blue" would give "bluebl"

I'm new to the Haskell so cannot form the logic or don't know if there's any function to do it.

One simple implementation would be to use cycle and take:

takeRepeated :: Int -> [a] -> [a]
takeRepeated n = take n . cycle
