None of the colours featured in your two pics

Hi Erin Both look like they will work. I think your challenge will be to bring some depth to the front of the house . With the colour being uniform its quite flat, so I would suggest adding some awnings to the front windows. These could also be a nice feature on the front of the house adding your personality. http://www.icietla.com.au in Brisbane sell some beautiful stripes. The other option was to have a base and top scheme that helped the building look a little lighter. A great transformation which ever way you go.

Think of introducing a contrast to the white - black being very contrasting, white not being a contrast and soft grey being somewhere in between (but possibly not quite enough, in which case you may need to go for darker shades of grey) . The analogy might be framing a picture or piece of art- If the canvas is really white, you wouldn't choose a white frame. Or putting on eye makeup- if you choose to put a colour on your lids and don't include eyeliner or mascara, your eyes will lack definition ! What colour is the roof ? Also ,have you chosen the white of the exterior yet because these two factors can help in your decision process.

With such a large house I think it would need some other darker colour along with white to help "ground" the look. Also, as mentioned above, pure white on an exterior looks very glarey - surfmist would be perfect. I would strongly suggest getting a colour consultant to help with such a large project - and get some mock-ups done with different colour ideas.
