"The rest are at best lacking and more often completely misguiding " ----- For most of us ,it depends how far down the rabbitt hole you want to go . But to many of us if we just mount them next to each other on a page is enough .
sure, but the OP was asking for assistance on determining shades, and how people collect isn't an issue here - he refers to scott, and it's my experience, that when it comes down to just inside the so called rabbit hole, the catalogue from the country in question is the way to go... and I can't imagine you don't agree to that.
but since you brought it up - for a collection that you refer to, a specialized catalogue isn't needed - but it seems to me you could live without a catalogue all together if you just want to mount stuff next to each other :)
I would not call a collector completely misguided or lacking
nor should you, and neither did i.. I called general catalogues misguiding when it comes down to the so called rabbit hole collection, again in reference to the OP's question regarding determining shades.
another good example is that scott apparently refers to paper thickness, but that varies in each print since paper production at this time wasn't completely accurate, and there's even examples of very fine, thin paper and "cardboard" thickness (which it isn't, just a term) - so if you go by that you end up placing things wrong.
i'm sure that's fine for most - but then again, no need for a catalogue, you can just willy nilly it as you feel is right.
but again, it was my interpretation that OP wanted the correct answer since he's gone to lengths of determining it himself - paper measuring and color analyzers.
as mentioned earlier some try just to fill a blank space which is fine
yes of course - but you brought this up, not the OP. He's obviously more serious and I've shared my knowledge to answer his dilemma to the best of my ability.
Call it misguided if you want ,but I have no interest in buying or having over 220 Specialized catalogs on my desk. That is not my goal as a worldwide collector ,it is to have a decent W.W. collection.
again - this has nothing to do with the topic... let's focus on helping him with the problem at hand?
