That would require a transition metal whose complexes are not coloured.
You could try vanadium or molybdenum. They also can undergo
redox-reactions (both 1- and 2-electron) and thus could carry oxydation
equivalents in chemical rather than complex bond. Molybdenum cofactor
(MoCo) is actually used that way in some exotic (but essential)
