Abstract
A Venetian blind is described having slats which have a selected color on one face and a lighter neutral, pastel or substantially white color on the reverse face, with string type ladders, one string of each ladder being colored to blend with the darker colored faces of the slats and the other string thereof being of the lighter color to blend with the lighter colored face of the slats. The cross rungs are also longitudinally colored in part in the same color as the darker colored string and the lift cord is of the same color as the darker colored string, so that when the blind is in the closed or partially closed position with the darker colored faces of the slats on one side of the blind, the strings of the ladders and lift cords blend with the colored surfaces of the slats on that side and are substantially unnoticeable.
