It's a lot too much and hard to compare all it would become messy and hard to read so I choose to only compare classic tabby to the shaded, shell and smoke, as well as black tabby to golden tabby, golden shaded, and golden shell. Please do learn about all the other patterns as well, knowledge is good. I'm not a member of FIFe, however when it comes to describing the colors, there is no standard who do describe the colors in detail as much as the FIFe standard, that's why I use this one as a tool for us all.

I tried to do it as clearly as possible, I will continue to check this to make sure I have not missed anything.
