Advice on Colour Scheme for Pillars and House?

I would appreciate your opinion on a colour scheme for our outside pillars wall and house. The house is a bungalow with mahogany windows, peat brown roof tiles, spoutings, facia, barriage boards and pvc garage door.

The masonary is all rough cast and painted magnolia. There is a base below the bell cast about 12 inches high from ground to bell cast. It has not been painted yet.

At the roadside entrance we have a set of pillars (7 in all) joined with a low wall. The pillars have natural sandstone pillarcaps.
The pillars surface is smooth cement finish with a rough cast part in the middle of each face. We have painted this roughcast part magnolia to match the house.

The joining wall has natural sandstone coping and its top part is rough cast (painted magnolia) and it has a base of rubbed up smooth concrete.

So far so good but now comes the tricky part. To tie the smooth part of the pillars and the wall base in with the pillar caps would I have to paint it sandstone?

If so the wall base then has to be done sandstone. Also the base of the house would have to be done sandstone. This would not look right. Can you help me sort this out. thanks
