Titanium, whilst difficult to tarnish, is a bit grey and boring. It
also has the reminder of the late 80's heated titanium jewellery in
fancy colour bands.

Carbon? now there is an idea. However gold is definitely good.

I thought carbon wedding rings were pretty much the standard choice.

Anodised, rather than heated, I suspect.

You really do get fancy colour bands if you heat titanium; I made some
jewellery using just that technique in the, er, early 90s.

Heated in an open flame. I've watched it done. Presumably the colour
effects are oxides, but why they're different colours and why they form
in bands and patches I don't know.

Its an optical interference effect - like the colours you see in thin
films of oil on water. The colour is related to the thickness of the
film which will depend on the temperature and time profile.

You can do it by heating or by anodising (the latter is more common as
it allows better control of and more uniform colours).
