I think you'd have a really hard time matching that same color.
What you could do is round off the other corner to match this side.
Being aluminum it's pretty easy to polish to a mirror finish and then
you could do a transparent matte or even a candy red finish.
Here's a friends old Bettinardi (similar thick shape) that I did some woop-woop to,
and powder coated a candy red....if you want a one of kind putter!
