My 2c worth... I wouldn't worry about trying to match your interior with your exterior colours... I say think long term, chances are you may be able to afford and want to change the exterior in 5-6 years, and then what, cream/beige again?... don't get me wrong, cream/beige is still in, but in the right tones (none of that yellowish colour)... and I agree with NOT painting the windows cream imo... from your kitchen photo, it looks like you're moving towards a more contemporary look inside... and if the cornices and skirtings will be white then my suggestion for the interior walls would be a warm light grey, e.g. Dulux Lexicon Half

I really like colorbonds wallaby... they have some contrasting colours listed below... this might give a dark enough look without being too dark. however would you consider changing roof and trims first and then see how you feel about the brickwork? It might be all you need to do for an updated look. I'd maybe do roof and gutters same colour and then down pipes in a colour similar to bricks so not to stand out..., garage doors maybe the woodland grey?

Yes go monument!and if you go for some lime acacias out the front (tall weeping or the low bush)it would brighten up you whole look.Also adding strappy green plants that bulk up would give it a bit more of a clean look. If you don't want to go monument on roof go a light grey and tie in with a couple of tall light grey planters on either side of your door. Pleas please please!find someone with a jigsaw and cut the tops off your pickets to give a cleaner look before you paint them. I'm stating the obvious but those security screens are pretty overwhelming,can you just have them on windows that can be opened,it might not look so busy out the front.

I'm with @dreamer The shapes, textures and tiles are the stand out features of the Tuscan style. White is calm, classic and majestic. You cannot go wrong
