It goes without saying, but minimalism does not suit everyone.
If, however, you are attracted to the idea of a tightly edited stash but worry it might limit your options, I have never found it to be so. A collection of a twenty taupes and fifty peachy-rosy nudes is more restricted in its imagination, an endless succession of tastefully neutral makeup. One naturalistic look is enough for me. I know you, reader: "But this one has an ashy undertone, while this has a subtle pink sparkle scattered throughout, and this is Rouge Bunny Rouge, a unicorn among unicorns, copy written by unicorns!" Bullshit. This is what the Buddha calls attachment, nothing more. If I get bored, I'll turn to makeup as a form of entertainment, but how will yet another taupe serve as any kind of palliative? Once you've got your neutrals covered (define a comfortable amount for yourself), let the rest go. Truth be told, you won't miss them.
