I have a 1/350 wooden Deck for a 1930s Saratoga (CV-3) and, while searching my local shop for a kit to go with it, mistakenly picked up the Trumpeter 1/700 kit. It's nice enough for the scale, with lots of colourful a/c of the yellow-wings period. What has me baffled is that the kit instructions would have you paint the plastic deck in some vague yellow shade. Is this correct, and if so how does one mix this colour? If not correct, what is right? Thanks much.
