Back, shoulder, saddle, breast, belly, thighs and flanks: feathers dark golden-brown with double green-glossy black lacing, the outer-lace running along the edge is broader than the inner-lace running parallel to it; the large feathers of the saddle and those of the lower breast also have a black stripe along the vein, which is also black at that location.

Tail: steering- feathers black except for the upper feather on both sides, which are irregularly patterned with dark golden-brown; coverts double-laced and moreover provided with a black stripe along the vein, which is also black at that location..

Note

When judging double-laced, attention must be paid to the color of the dark golden-brown, an even ground-color is highly valued.

The presence of a complete triple lace is not considered a fault in older females.

Serious faults

Too heavy, irregular, not completely surrounding outer-lace. Lack of inner-lace. Too light dark golden-brown, dark reddish-brown or hard rusty-red. Too much brown in the neck. Strong peppering in dark golden-brown. Too light vein-color.
