Just depends on what you like the look of when combined with ghost really and then trying to find a het ghost with that gene.
I like ghost black pastels, butter black pastels so I'd consider that for example as a good long term project for me.
And if you get a female black pastel ghost ( or het ghost ) the triple is not too shabby either;

Add in pastel and I think it would look even better.
Like this with the broken up pattern and the high oranges;
