I hear ya... but the thing with the neutrals is they can hugely expand your existing choices - providing a blend, a bend or a deepening of what you have... because right now the only way to really mix it up is to put the purples in with the greens.
Like, fiction and nightlight with woodwinked and shroom would make an amazing smokey dewy eye. Also if you have an eye for the duochromes like Stars and Rockets or Club and aren't sure how to make them really pop, greys, browns and blacks under them bring out their cooler properties.
So if you got a basic brown, black, grey and something like Shroom... a huge expansion for very a comparitively little investment.
