A colour called paperbark. It has green undertones so works with both the roof and windows, although will look nice against the garden too. Another is bushland, both are colourbond colours, and available in paint too.

Hi I recently painted a small fibro house and I recommend not going too dark with the colour if is a smaller place as it looks. I chose an ochre colour and it was too heavy for the cheap, light material. Still, I kind of liked it as it warmed it up a bit, given it was in a dense, wet foliage. If I did it again I would choose cream. No offence to the other contributors, I like grey, but I wouldn't do this kind of house in grey. Grey looks good when the materials are good quality, but can look jail cell if not. If you like grey, I suggest a very pale grey. Cladding might really help as Sarah H suggested, it can be a little depressing to come home to such unprotecting looking exterior. I would do the lattice at the bottom a darker colour to 'ground' the house.

there are some interesting putty grey colours in the knots of your floorboards. I reckon it would be worth holding some paint swatches up to the boards and see if you can find one that ties in with those driftwood tones in the timber . Then order a sample pot in a half or quarter strength version of the matching colour then see how it looks. Otherwise it is so hard to go with colours people have named, as every space has different light. If you are happy with the colour of the floor boards, let them guide your choice and you can't fail (as long as not too dark). :)

To be a voice of dissent, have you considered soft greens or green-grey? I've got Baltic Pine floors, pine cabinetry, stainless steel appliances, and black tiles in a BRIGHT west-facing kitchen. I went with Taubmans Swiss Meadow double strength and it compliments all the different elements. If you don't want something "obviously" green, check out Taubmans Alpine Snow (double) - it seems to change colour in different light. It's a pale green in full daylight, but looks soft grey at night.
