<<N1111.1 - Almost Medium Blue>> is too confusing. 'Almost Medium Blue' could denote a color between 'Extra Dark Medium Blue' and 'Medium Blue'. Which side of Medium Blue Almost is on is not clear.

This is a much more appropriate description

N1111.1 - Almost, but lighter than, Medium Blue or ABLTMB (pronounced abbletomb) for short.

In the same vein, N1111.2 - Closer Yet, but lighter than, medium blue or CYBLTMB --pronounced Sybletomb

BTW, I need an abbletomb $1 Silver City for my collection. If you don't have that, I take a Sybletomb. They are close, you know

Simple, isn't it>
