We're mixing some terminology here - not exactly apples and oranges, but more like apples and apple pies.
The first site provided, the Ship Camouflage site, provided colors only. That is referred to as the Measure. Measure 21, Measure 32, etc. Some Measures are the same for every ship, and some require speacial Designs (also known as Patterns, and requested in this thread as "drawings"). In all cases, the Measure is the palette of colors to be used, and in some cases, the Measure will prescribe where those colors are to be applied. And in other cases, that palette is to be applied in particular Designs.
The second site provides some of those specific Designs, which were custom-made for particular ship classes. So a Design 10A is for an Aircraft Carrier, specifically drawn for an Essex class. (And just to keep it fun, sometimes a design was used on a different type of a ship, but every rule has exceptions). The Designs were, however, only meant for a particular measure. I do believe that you will never (There's a cocky statement to make!!!) find a case of a Design 4A used with any Measure other than 32. (See the Nautilus site to see what I'm referring to)
I will keep this short, but it could be a very long dissertation.
