First of all, pictures. No idea what you are talking about with your color descriptions. Herringbone weave? Blue silver gray with black hackles? Not a clue what you are talking about.
This hen is Blue, but not an Orpington with those white earlobes. Likely a mixed breed. No telling what is under that modified extended black.
Thiis is the blue orpington.
That's cuckoo/barring.This is a malines rooster and hen. Mating malines rooster to blue orp hen. Do your majic.
The Blue gene can have an inhibiting effect on barring. Makes it more difficult to see the barring, and it can prevent barring from expressing uniformly across the bird, limiting it to primary feathers, hackles, and tail feathers. Both the Blue gene and barring are dominant genes, but they affect pigment in different ways. Blue only affects black pigment, diluting it to shades of grey. Barring is a modifier gene that removes pigment entirely, producing 'bars' of white. It's not really understood how or why Blue can have such an effect on barring.

One of the chicks from those two birds might look something like the cockerel on the far left of this picture (without the beard and with a single comb instead of a modified pea comb). One parent was splash and the other was cuckoo - this bird was extended black with one copy each of blue and barring. His body was blue while hackles and saddle feathers were barred... a perfect example of the inhibiting effect that JuneBugGena was describing.
To get a light buff (not assisted with dominant white) as in a buff orpington, the E locus would have to be changed in the polish from Birchen to wheaten or wild type. The gold laced polish is a darker buff color because of the black that is in the feathers. The dominant white gene removes the black so you get a mixture of white and dark buff which produces the light buff color.
