Great advice above from MB.

Vivid white is extremely bright outside, I can't suggest enough to use a tinted white. You will need sunglasses otherwise! Surfmist works pretty well with most colours but can throw a slight green.

Dulux Natural White will be good, but very bright.

If you can choose something other than Colorbond colours here's a few. Just make sure the paint dept confirms the tint is for exterior use (can be a problem for exterior paint tint, even if it's an exterior paint).

Dulux colours:

Todd River - newer one, I haven't seen it large scale. Doesn't throw green.

Simone Weil - throws a slight blue, but quite a neutral grey.

Tristan - brown based grey

It would look amazing if you could clad the LHS grey section (with the two windows in it) in a horizontal timber cladding to match your door. Probably not an option though!

Thank you! I don't need to have colour bond colours, i'm just scared to pick paint colours as we have had a bad recommendation from a painter before. Unfortunately my husband has plain taste and wants it all to be render. :)

If you have a sheet of building material (sheet of fibro or something that size), get a few sample pots & paint it.

Leave the painted boards outside to see them in different lights, you will be suprised how light colours actually look outside, especially whites.

Good luck!

While shale grey is a colorbond colour it is very popular for an external colour and goes really well with basalt for the same reason. White on a house when in full sun will be too bright.

You don't think basalt and shale grey will make the house look too grey?
