An article by Marilyn Lockwood may be of use to you. It includes images that attempt to illustrate the differences between pigeon's blood and other dark reds, such as Ruby and Cranberry. The chemistry of making glass is such that there are all kinds of variables which need to be controlled to create a consistent color in exactly the same shade time after time, which is why glass companies were very secretive about popular colors they patented. Therefore, a shade called "ruby" from one company might be slightly different than a shade called "ruby" created by a different company.
There is also a 2nd article which compares dark reds by Albert Revi. If you aren't able to access these articles through your local library but are interested, let me know and I will send them to you.
