There are around 6 standard colors in the silkie breed with a few more being worked on like Cuckoo. Most breed true to color except for blue which gives only blue, black & splash offspring of which all black & splash breed true to their color. If you cross two different colors apart from the Black/blue/splash, you get a rainbow of strange colored birds. They are still pure silkie but their colors have no names (or too many with everyone renaming their odd colored birds). You can't breed two standard colors & get a whole bunch of other standard colors from the cross. You get a mixing & blending of the colors.
