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.

Just as a tip, those dark colours in your light brick arent' grey, they are a deep purple/brown also known as Burnt Umber. The midtone colour in that brick is also a purple brown in a natural mineral, in artists land that colour is called Indian Red, other similar hues are perylene maroon and piemontite. I'm an artist so very used to seeing different colours and their undertones. Colours that will go with that will be blacks that are actually red or purple based. So NOT monument which is a blue based charcoal. Blacks come in many different tones and it's important to match the undertone to your brick for colour harmony. Blacks which are complementary or blue based will stand out more but may not go as well. Which is why the grey blind seems uninspiring, it's a blue based grey. I'll name some colours in the Taubmans brand. I didn't pick Dulux because it has an abyssmal colour selection atm. Phantom Myst and Fable would both be good blacks to use on your home. Ruby Rose and Redwood and Russet stone would all go with the brick colours. Unless you train your eye to see hues and undertones it's very difficult to spot them which is why a colour consultants have a job. If you're interested learning colour mixing is fascinating there are even hues like red-blues which sounds paradoxical but ultramarine is actually a red based blue' A hack for creating colour palettes super easy. If you have Photoshop you can show it a photo and it will automatically create a perfectly co-ordinated colour palette for you of 6 or so colours which are exact matches to the colours in the photos. Any photo at all, and it will spit out pantone colour codes for you that you can take to paint shop and have them mix up. It picks up some dark, mid and light tones and you can have it create monochromatic, complementary, split coplementary etc palettes that work beautifully.

The only part that possibly should have been accented is the verandah section. Start by giving it all and undercoat to cover the maroon. I’d paint it all a white that is right tone for your blue roof, maybe white on white and then accent the porch in a darker shade like Dulux linen white Do you know what the blue actually is?
