Still need help though, The ACADEMY M3 Stuart is supposed to be:
Dessert Yellow, no ref on the chart (above) but Tamiya has a DY XF-59.
Dark Green, there are in all 4 references but I will go for XF-61
Slate Grey, no refs, according to the Box Colour scheme it should be 60% Light Blue and 40% Medium Grey,
Light Blue has no reference, I will use XF-23
Medium grey has no reference, I will use XF-20
The box art is really blueish in the "Slate Grey" areas, XF-23 is not half the way there...
This still needs to be configured :D
