The major issue with Excalibur is that the gold on the hilt rarely matches other gold items in the game, and almost NEVER matches any attempt to dye a piece of gear gold to match it.
I've found that most of my paladin glamours revolve around bronze rather than golds thankfully a lot of nice models also follow this. I use my excalibur with my Meliadoul set because there's almost no metal at all to worry about and the gold is "close enough".
