Haven't a clue what I'm doing. - But Ti, a variac, a diode and a
bucket of Pepsi will give you enough of a result to be interesting.
Vary the voltage to vary the colour.
Obviously this is just an interference film, not a dyed oxide layer.
I too would be very interested to hear of the real processes for this.
Most of my Ti colouring is done with heat (lovely deep blues), but I'm
decorative not structural and so I don't care about any heat treatment
