I am creating some small pieces of furniture and would like offer these in various colours, with most pieces being 2-4 colours on average.

I have an item that is black, white and brown, but if a client wants to see it in red, white and blue, can I set this up so only 1 click is required?

Thanks all

I'd use duplicate layers, with the alternate colors on each layer. If each layer has a full page background, the higher layer will obscure the lower with one click.

e.g b/w/br on layer one, with r/w/bl on layer two hidden. Showing layer two will cover layer one, hiding the b/w/br.
