The new iMac colors are beautiful WHY can't everything come in the same set of colors?!? 1 set of colors for iPhones Another for watches Another now for iMacs

The new iMac colors are beautiful WHY can't everything come in the same set of colors?!? 1 set of colors for iPhones Another for watches Another now for iMacs Another for iPads I want to color coordinate everything. If all casings for the most part are the same aluminum the paint process must be the same? I want my phone to match my watch to match my laptop - period.
