Help with exterior house paint colours

[quickscribble]

I've been struggling to decide what colours to paint the exterior of our house since we started renovations three years ago. Painting the house - the gables and other bits of woodwork, and other rendered parts - is one of the last things we'll do. I want to get it right as I think it could make a huge difference, it's a slightly strange-looking house. I need to somehow see the house with the various colour combinations I've been considering - does anyone anyone know a way of doing this - I can't use/don't have photoshop. Thanks

Just to add, I've looked at the descriptions of all the apps they are available and can't see any able to do exactly why I'm looking for.

So there's no red brick or large areas of grey slate visible - just the colours you choose?

Thanks for your reply. There's a bit of red brick, and also lots of hung tiles. Also the tiles on the roof obviously, which are terracotta also.

The problem is balancing out the top and bottom of the house with the help of the right colour. The ground floor is of smaller proportions and the first floor propped up with pillars. So the house has a top heavy look to it currently. In other words it's not as simple as seeing what colours look good together with the help of a mood board..

You probably need to post a picture
