Thanx for the info, I will go check it out.
As an experiment I looked at Humbrol yellow sand but was to "yellow to me" so I tried Tamiya 74 enamels.
Here is the base with the highlights on it

Then I sht the tamiya over it in thin coats till I got an even look with shadows just showing through, the sides and bottom O added a drop of black to look like it is bleached a little less.
This is an interesting colour indeed, in bright sun it looks very grey

But indoors where it will be viewed mostly the clopor changes to a more tan.

Now I need to weather it a little and complete the hull.
