Introducing the Dominant White factor into
Vorwerk pattern; it dilutes black areas on a chicken to white.
P:
Red pyle Dutch bantam * Vorwerk bantam
e+/e+,co+/co+,I/i+,s+/s+ * eb/eb,Co/Co,i+/i+,s+/- plus (het?)
hackleblack melanizers (Ml, charcoal?)
* 
F1:
White patterned Buff Columbian
e+/eb,Co/co+,I/i+,s+/(s+) plus
heterozygote (multiple?) hackleblack melanizers

Backcross both males above to mother Vorwerk
bantam

red tint on the body.
I suspect that homozygosity of Co (and eb) also improve the hackleblackness.
Pullet:
