Deleting lines of a file if they exist in another file

I have a reference file that needs to remain static and another file that may or may not have duplicate rows that match the reference file. I need help with a command that will delete any duplicate rows from the second file while leaving reference file intact

For example reference file would have a list of colors -
red
green
blue
yellow
purple

And the second file has the follwing list -
red
orange
purple

I would like to see the second file end up with only unique rows -
orange

any help with a statement would be greatly appreciated. Thanks

purple-send-async method-name [type1:value1] [type2:value2] ... DESCRIPTION
