I want to start a color project starting next year for this color because I think it is gorgeous and pops up every once in a while but people aren't sure what to do with it

She is from partridge eggs, but is sort of a mix of buff partridge and paint. You can't see it very well here but she has blueish silver mixed in and dark blue/black spots.
How would I go about doing this? Is it possible to make it a recognized color after a lot of working with it? How would I register it?
Also, genetics wise, what should I try breeding her with to get more? I also have a blue splash that should be good for it too. Maybe a buff roo for both of them? or partridge for my splash and buff for this one? All input is appreciated!
