We have the same coloured tiles. We painted with the colour called buff tone, I think dulux, if not, taubmans. Trims in aspen snow, and our gutters, front/back door a contrasting darker blue-grey (can't remember the exact name sorry) I'm really happy, depending on the day/light it comes across a either grey or bone. We've had stacks of compliments too. In this photo, you can't see much wall sorry... but you get a little bit of the idea. This particular day it was looking more bone. Good luck!

Terracotta roof tiles. Then you could either go with steel greys and blues, varying shades and tones of terracotta or a combination of both. Have included some Dulux colours showing how versatile terracotta can be to perhaps give you some inspiration...

When you say Peninsula, where do you actually mean? I like the colour you have now. So repeat that or just a shade darker. Fabulous looking home and location.

Progress report…have gone against general consensus and opted for moving away from the traditional colours. The painting is not yet completed but am personally loving the transformation.
