The Scott's Specialized Catalog as well as the Datz Catalog of Errors only lists major errors, defined as missing rows of perforations, missing colors, or other major production errors. Here is the "missing bee" listed in Scott as 2281i with the black omitted.

What you have is a color shift, known as the "Slow Bee". Search for 2281 Slow Bee and you can find other examples online. There is also a "Fast Bee", "Low Bee" etc. Color shifts are much more common than colors missing, and they are often available in various amounts of shifted colors, so it makes them hard to list them in a catalog. They are of interest to some specialists, their value usually tied to their scarcity and/or the degree of the shifted colors.
They are a fun addition to any collection, so enjoy the find.
