Standard mid blue, spot of white, to roughly match the colour of the 'Windows' banner, top and bottom of the monitor screen. That should do it! Don't matter if it appears a little too light, it'll stand out more in the shadow of the cockpit. Remember the smaller scale - it'll have an effect on 'scale colour', so don't be frightened to experiment with a lighter dry-brush over the cockpit parts. If you think you've overdone it, just dry-brush again, with a darker shade - piece of p!ss.
