House Paint Question....

So I stay in a complex and it's time to paint the outside.

Problem is we have a fixed roof colour :

Similar to the colour on the left.

Problem is that we're really struggling to find matching colours... The house is currently white which goes great with the turquoise, but white is a b!tch to keep clean and just doesn't work with dogs...

Any ideas from someone in the know? We would prefer natural/earthy colours

Thanks!
