Yes -- several.
There are two different types of black HH. One type is black on the surface, with a brown under layer (this is frequently called "tea core"). This black will show brown when scratched and/or heavily worn. Many like this vintage look. The other type is black on the surface, with a black under layer (RMC calls this "deep black"). This black will remain black even when scratched and/or after heavy wear. I personally prefer the deep black (both my RMC black Shinki HH and Himel black Shinki HH are deep black).
I like tea core stuff for boots, but agree that the true blacks tend to look better for jackets. FWIW, that HB for SE Kensington was a brown/ black.
