Also, with OBW, you can reduce or enhance the dominance of a colour by how you design the layout. If you group all the dominant orange blocks together (like I have, top left) they'll make more of an 'orange statement' than if you spread them about through the quilt. I'm partial to the turquoise-blue in the fabric so I've given that the starring role by putting it central and will probably enhance this further in my choice of border colour. :-D
