I only break black spokes. Black can cover cheap crummy metal.
It's not the colour that's the problem, it's the quality.
Originally, spokes used to be carbon steel, not stainless.
This is a more reliable material.
They were then galvanised or chrome plated for weather protection and the look.
In the 90s, stainless spokes, from being premium, were creeping downrange, and by 2000, wheels nearly all had silver stainless spokes.
Cheap stainless work hardens quite fast - 2 years riding, they are snapping at will on the (higher tension) drive side rear (before disc. Now they often snap on the disc side trailing, front and rear)
The rush to fit black spokes around 2010? probably led many brands to find a cheaper source of black stainless spokes
- new components are often more expensive at a given quality point than ones that have been around awhile.
Quality black spokes were and still are as reliable as quality silver.
