Colour conundrum

So, son no. 3 has finally left the shed in the garden otherwise known as a holiday let for 2 and I am busy refreshing it for the first paying guests on Saturday but I've lost the colour chart. Instead of the obvious magnolia I went for 'milk white', 'antique English white' and 'imperial white' for the ceiling, walls and woodwork ... but in what order???
Our 3 sons and their partners are currently sailing in one boat in the Mediterranean. All our eggs in one basket comes to mind rather too frequently.
