I bought dulux mineral haze 2 for the walls, and mineral haze 3 for the ceilings. when I saw the haze 2 on the color swatch looked really grey, but on the walls I'd a blue gray. My questions are, 1:what do you think?, do the colors look good and blend?, 2:do you think I Should paint the hallways the color of the walls or the ceilings? ,3: and lastly, if it's not too much trouble, my sofas are milk colored, what color of curtains/drapes will be best?, grey or cream?; I'm open to suggestions. pls help, I need to make the decision tommorow. Thanks guys!!
