I am so stuck. So much choice, I can't make my mind up. The hall is quite large and is presently perfectly taupe. It needs to de a Dulux colour. I like dusted moss 1 but not sure if that would be too dark, then I like bleached lichen 2 and 3 also. Then to put a spanner in the works, I bought a tea canister with the most beautiful light blue/grey ombré effect on it and got to thinking about a light blue grey. Any suggestions? For info, rest of house is blues/greys/white
