Paint your wagon TARDIS
Celestial Blue 3 didn't look right, so I went and got some Celestial Blue 1. It should be a bit darker.
And it is: At first I thought it was a bit greeny (the flash from the camera has adjusted the tones somewhat) but the more I look at it the more blue it becomes. I've painted one side and round the top.
One thing I forgot to mention on Page 15 (and if you look at this picture you'll see what I mean) is the roof doesn't fit on anymore, as the paint makes it too wide for the top of the corner posts. The little door also doesn't shut, so I've sanded some off that and it should be OK.
