This made me smile. The Phantom remains among the sturdiest heroes across the globe, in whatever color your prefer.
Here is the red Phantom from Italy. For whatever reason he was given a red costume in that region and it stuck. He's sure easy to see.
In Sweden The Ghost Who Walks is blue. Maybe it's because it so much colder up there, but still the Phantom is, still the concept holds.
UPDATE: It's confirmed (by the artist himself) that the Phantom cover above by Reno Maniquis is an homage to the vintage Detective Comics #241. Thanks Reno for brightening our day.
