For out-of-print titles, I'll be marking them as Red, unless another release still in print (e.g. re-release, complete collection, standard edition, etc.) used the same disc masters, even if it's released by a different distributor.
Of course, I may have missed a few titles, some intentionally, in case a title that was only released in a Collector's Edition would be re-released in a Standard Edition (especially with non-Funimation sub-licensed Anime Limited titles), unless a distributor confirms that there are no plans for one.
