Perl Regex Matching expressions without set of strings [closed]

I need a Perl Regex to match expressions that not have any string from a set of strings

As a example, suppose the set of strings {"red", "blue", "white"}

"A blue sky" Not matching the rule "A green house" Match the rule

The regex (red|blue|white) match the rule when a string is present, but I need the opposite
