Great improvements! I'd colour match to that lovely pale taupe brick in your brickwork Perhaps half strength dulux ricochet or full strength cb dune or wallaby

I agree with not going dark, the house is already in quite a lot of shadow with the deep & low eaves, so I do think the butter colour actually works quite well in that regard. But it probably is a little dated, use my favourite colour of all time (drumroll!)... Dulux Dieskau. It's a light taupe/warm grey and looks beautiful with a fresh white like Casper White Quarter (which I have used!). The white will keep it fresh and bright and of course tie in with your window frames. Then I would choose a 3rd dark colour that will tie in with your roof just for your guttering and garage door. So fascias, eaves, posts & gate in white.

I wouldn't paint the bricks, I think grey would look great on the trims and roof, are they fly screens on your windows? they look quite unique plus the screen door is great, love the bench also, it's a lovely house , I would try to compliment those unique features

There are lots of paint manufacturers apart from Dulux, and hundreds of whites that it could be. Unfortunately the natural light in the photo, the type of camera, any photo editing, and the adjustments on your computer screen make it impossible for anybody to say with any accuracy what the colour may be. The only way to find the right white is to get samples and make your own judgement on site. I always think that Perth light seems stonger and brighter than Sydney light - possibly due to Sydney's airborne pollution in the inner city? There are lots of online resources by various paint manufacturers about choosing the right white, but don't make selections from an online digital image as it won't be accurate.
