Is this normal for forged conrods?

Is this normal? just heat that would have made them that colour?
They were removed from a fully working running engine, so i presume they are good?

That's just from the oil in the sump I believe.

They look cool, with the multi-couloured sheen halfway up-does it matter?

You took the engine apart just to look at the colour of your conrod? That dedication...

Looks similar to when metal is tempered.
