black anodized steel is a common thing, all you have to do is find out how
it is done and do it on a small scale for spokes.
hope this helps

Nowadays with all the spoke options I am hard-pressed to keep, or
indeed, find stock of all the permutations. How do they blacken spokes
and can this be done in a workshop as and when needed?
