Is there an efficient way for adding colour options to a specific list? In our case, we are trying to list four colours for bedsheets, pillowcases and duvet covers. The other products (books, soap etc), are available in one colour only (other items may have different colourways in the future).

Will adding a global system change mean that every product is suddenly available in four colour, or will products only show multi-colour options if they are added via admin?

As there are hundreds of products to add, it's be useful to know this before tearing up the global settings!!!
