for this example http://fancyproductdesigner.com/product/poster/ is it possible to have the color variations in here using Multistep Product Configurator and it will redirect to the product which is attached to the color chosen?

I hope I have understood you correctly

You can use Multistep Product Designer to choose different color variations of a product (for example the poster) and display them in a Fancy Product Designer where you couöd edit the views like you would normally using only the Fancy Product Designer. Take a look at this demo: http://fancyproductdesigner.com/product/sneaker-mspc/. If you need any further help on this please open a ticket in support.
