We got so focused about the inside of the house and the bricks, roof tiles, etc, but didn't do the checking of colours by going to a paint shop and getting a sample paint.
Anyway, we can still do it this weekend, as we can still change few colours during contract signing

Sorry for all the bother, I know that you were limited with the colours that you have.
We were shown the fan deck and we got overwhelmed.. hehe.
So we just concentrated on the grey/green and grey/blue ones and chose from there.
Will prepare an image of all colours that we chose so you can see.
Thanks again!
