Why doesn't this work?

val moreColors = arrayListOf("blue, red, yellow, pink, teal, red")

// Create a new array list to store the colors without "red"
val newColors = moreColors.filter { it != "red" }

// Print the newColors array list
println(newColors)

shouldn't be

arrayListOf("blue", "red", "yellow", "pink", "teal", "red")

?

No idea why it wasn't working for me initially
