It looks very similar to a Dulux colour called Tapestry Beige. I would describe this colour as a grey-beige, sort of taupe - a cool brown.

Go grey as advised above, don't paint window frames if they are metal but leave alone, plant sasanqua camelias along the side boundaries (they can be hedged) to screen out neighbours & add greenery plus colour, landscape the front. Don't do white stones as they look dirty after a while and are blinding in the sun. I'd get rid of the stones altogether. If you are a gardener, put in box hedging and some standard roses (yes, I know done to death but they are charming), or draw up something on paper first - play with shapes. A garden makes a house look good.

I'd definitely leave the brick and the roof, it looks like a good, solid and classic house a and the front door would come up beautifully in a smarter colour. I'd paint your front door, gutters and garage door Dulux Monument and it would look fantastic, particularly with your brick and roof couloirs and that lovely sandstone. Then the gables in the same sandy colour as your posts, though if it's too yellow-creamy you could use a warm grey taupe like Dulux Dieskau. Replace the coach lights with a sleeker but still classic version like Beacon's Southhampton and an additional pair either side of the front door. Replace the urns with say 3 simple tubular pots of varying heights on the left side with some interesting crassula and rounded Japanese box. Trim your hedge right down and thin out to shoulder height. Not sure if you can replace the finials on your fence as this Victorian style doesn't suit your house and is a bit dated. Then rip out any ratty looking plants (poor roses always look ratty!) and replace with plants that are ideal for the aspect - if they're in the shade only put in clients that in part shade even magnolia little gem is versatile. Otherwise a lovely sweet viburnum will add softness and bright foliage. Plant mondo grass in the tall pot and remove the pew bench and rectangular planters and get a new small batch of fresh pebbles for between the square pavers. You could even put an interesting bench (or that pew) along the wall on the right of the front door, style it up with a couple of outdoor cushions (KMART even have some smart stripe ones). and finally get the roof cleaned but otherwise leave it! it's a great house, it won't take much to make it look really fresh and stylish.

It's an open book really. Since you are changing the gutterings and the windows are plain aluminium you can choose any colour your please. It'd personally go with a classic neutral tone, not white, which can look very dated very quickly and shows up every bit of dirt splashed on the side of the house and blown in on dust.
