A YH.WB.DFYb/Bb with a BH.WB.Bb will give you
male that are:
SF Pastel Blue which will visually be white bodied because of the WB
SF Pastel/Blue which will visually be yellow bodies because of the WB
and your hen chicks will be:
Pastel Blue which are visually white body
and Pastel/Blue which are visually yellow body
To get Blue and Normal chicks he has to be SF though I'd wait till the chicks color up more before deciding that is so.
Nice looking group of birds
best of luck
