You got it just right!!
Splash with red patches should be called calico just becouse that's what their colors look most like compared to the color of cats.
Torts should be the gray with autosomal red in them. Your rooster is tori and stunning!! Love that color in him

if your looking for a mate for him look for grays or silver partridge with softer Brown or blurrie red on wings and chest. Males are much more brightly colored with splashy color. But I think there's tons of room for improvement if someone's willing to work on it. They could be stunning!!
For better or worse, I think most if the silkie breeders out there now are working hard to keep there lines as pure and solid in color as posible, and ignoring the posiblitys of Inproveing a mixed color like calico or torts.
I hope you decide to work on them
and lots of luck
