Exterior Colours, Advice/Help Appreciated

Hi Everyone

Great site, been going through it for a while.
Building our first home, bricks done, roof next.

colours :
Midland Milano brick (limestoney colour) (brick all round, no render)
Sambuca monier prime roof tiles
Monument gutter
Monument fascia
Paperbark downpipes
Monument garage door
Paperbark entry door

Too late to change roof colour, but able to change garage colour and I really like the Dune colour...
would Dune look OK with the milano brick ?
also I like Paperbark, perhaps match the entry door to a paperbark garage ? Or do the same with the dune ?
OR should I have the entry door as Monument and the garage either dune or paperbark ?
The reason I'm asking is that I'm terrible with colour co-ordinating and the 'blackness/heaviness' of the external colours has been niggling at me for several months now.

Any advice/suggestions/tips/feedback would be appreciated,
thankyou !

I'd go with the paperbark or Dune for the garage and match it to the downpipes and entrance door.

That is just my personal preferance thoug
