It can be. I've seen some shades that are similar between Mac and minerals but you may have to check MACs ingredients as they may or may not use dyes or pigments in addition to the mica.

Oh another point is that it would depend on what base you use too. Some other ingredients common to eye colors can vary widely on what they offer as a base. There is no one "fit's all" ingredient.
Some offer shearness with great hold, others offer not as good of stick and maybe silky. It really depends!
