I assume you mean the lacing.
Both of the birds above are Satinette Classic Old Frills.
Satinette specifies a pied pattern where only the tail and wing shields are pigmented.
Blondinette, seen to the right on the breed standard portrait, is full body marked.
The lacing on a bird like the Blue Lace Satinette in the first photo is its own wierdness combining a bronze variant called the Toy Stencil gene with Checker or t-pattern.
The brown hen in the second photo is what Frill Stencil does to a Bar.
Bronzing is dominant, replacing black pigment with red usually in the wing shields.
Toy stencil replaces the bars (and checks, since they extend from that) with faded bronze, if only one copy is inherited. Two copies bleach the effected area.
Frill Stencil does the same to the tail bar.
Classic Old Frills are required to express both.
