It’s hard to tell from that photo. Can you post some at diff times of day. Screens show different colours. What colour is the roof and each colour sample. There is no right or wrong or perfect colour just one you don’t hate or like slightly more. We each have own preferences

Your house looks lovely but as above needs photo with sunshine. Would suggest you get a Dulux colour consultant to call out and help pick a colour that will work with your new Surfmist roof.. They have a deal to refund this service against paint purchased from them

Looking at your photo as the only reference, I like the current brick colour. I would remove the very busy security screen with a mesh screen door. And spend time doing lots of landscaping. The roofers rubbish is distracting the actual colours of your home in this photo. If you really don’t like the current colour, I’m heading towards the colour on the left wall.

Great house, if unsure get help from the colour experts at Dulux, you can book a consultation or you can chat online, show your photos and they are very helpful in giving you ideas that will go with your roof. I have used the online service and found the perfect colour, something that I would not have thought of.. I understand your hesitation, it’s such a huge decision and getting it right first time saves you stress, time and money..whatever you choose I am sure it will look beautiful.

Before I even get to your house , is that a street or driveway in the foreground of that photo , or is it an outdoor table or similar ? The 'dimples' look like dew or rain , rather than a driveway .

The letterbox is plain and simple , so I'd lux that up a bit , go with a new one , maybe in a colour , or maybe even your house number or similar on it , in a bright colour .

As others have said , the garden could do with a bit of a makeover too , some newer plants withssome variety -- a yellow flax , a red leaved taller shrub , a bit of variety .

I think the bricks colour is okay , and even the screen door fits the look , but I'd bring in a bit of colour -- do the window frames and sills in a deep 'metallic' charcoal , the gutters probably the same ( it'll make your house look longer and lower ) , and I'd do the screen and door in a bright red , but you probably have a favourite colour -- just not grey haha !

It'll look modern but not too try-hard , clean with a bit of variety and focus .

Thank you everyone for your help, i have gone with the suggestion of grabbing a dulux consultation and seeing what they think :)
