Wood window blinds have are natural variances in the color, grain, etc. that can cause dye lots to vary in color. Although we consider these variances to be minimal there is no way to assure an exact color with stained wood window blinds. If you are ordering a stained color finish be sure to purchase all your shades at the same time so they are manufactured from the same dye lot. We will only guarantee a color match for wood window blinds that are purchased together.
