Hi, I like the overall concept of the darkish grey, it suits the home. I am a colour consultant and have been working with the Dulux range for 17 years and you are on the right track with the Guild Grey. The Dulux Signature will give you a dark blue house. Another option if Simone Weil which is just a bit lighter than the Guild Grey, if you find that one too dark. Sample pots and A4 brush outs onto white cardboard are the best way to decide, because computer programs give an overall impression of the "look" but are not accurate with colour choices, you can't beat the human eye. All the best, it's going to look great.

Thanks for all of the suggestions everyone. Given me many ideas to think about

I'd rethink the red and cream colours. There are multiple threads here with people trying to change those exact colours. They are a bit dated but have what you love.

We are finishing off the remaining garden bed of our front yard to match the other side - roses just didn’t fit. We want to take the opportunity to update the colour scheme on the coining, fascia, gutter and garage door. Also upgrading the front screen doors to a darker colour like monument. I am a fan of griege but want to make sure I pick the right tonings. I love the colour scheme of the mansion below. Would this suit?
