i was trying to keep the "genes" simple because it gets confusing fast when you add all the double sets of genes. Your is more accurate, i have seen the website you referenced many times myself and it is a good sight.
The Splash i was talking about is not the golden necks....i was meaning the blue splashes that appear visually blue with white mottling Like this:

Also Ideal has both true golden necks and what your calling splash golden necks, so you could end up with either or..basically they are not set up to keep all the genes seperate, so you could end up with a MF looking bird split to any of the other colors potentially.
Oh, okay. I was confused because I did think you were talking about the Golden Neck Splash. That is why I call the Gold-Based Splash "Splash Golden Neck" as to not get them confused with the Black-Based Splash which is commonly just called "Splash".
I don't know quite as much about the black-based birds as I do the gold-based. To me the one in your photo looks just like a regular Bl/bl Blue Mottled. I thought that the Black-Based Splash birds look like this? But I could be wrong. http://cdn.backyardchickens.com/1/1d/1d60e13c_18946_tx_mfc_splash_blue_duccle_006.jpeg
