Easter traditions in Portugal do include coloring eggs, but it's more about the breads and the rituals. In Braga especially, Easter is NO.JOKE. There's almost a carnival-like atmosphere during the week prior, including mannequins of John baptizing Jesus in the Rio Este (the East River...which is more of a little canal and no where near deep enough for mobsters to dump any bodies in

) I have pictures of them somewhere and thought I digitized some of them but I guess I didn't. I'll see if I can find them.
On Good Friday, everyone is in town for the procession, but this is a very solemn procession, with chanting monks, statuettes, prayers, and long periods of dead silence. Do you know how hard it is to get silence from a crowd of Portuguese people?? Easter itself is festive and involves lots of dressing in your finest and promenading through town and hanging out in cafes.
