I have no idea with these things, but I can't see how WG will look so bad with charcoals and greys!!!
This is the problem with greys and charcoals, nearly every charcoal has a slight undertone of another colour, you don't notice it until you put it next to another grey or charcoal with a different undertone.
Therefor the Woodland Grey looks green next to all the other selctions internally because it has a green undertone and none of my other selections do. The bathroom feature tiles have a slightly blue undertone.... so the blue undertone now stands out against green looking windows.... it's not pretty.
Donuts, your Woodland Grey on your facade doesn't look green because it's not with any other greys or charcoals. In my travels over the last few days, I've noticed Woodland Grey is the MOST changable colour out of all the colourbond, in that it will look very, very, very different depending on what it's with.
So with all my charcoals, I'm having green windows.
I'm still hoping I'll be able to use Monument from a different supplier....
