Mutation and advice help

[rainbowCro]

Well i recentl saw thus budgie in pet store and it kinda reminds me to rainbow some types atleast by its yellow and bluelish style. I heard and what i read since im learning that it ia spangle double factor.. But i wanted to know if i can pair it to some colour to try gettin rainbow kinda chicks or future budgies maybe, so if it ll be worth buying it or i should look for another mutations that are closest to pair to get the rainbow type... They r beautifull, i alrdy own one rainbow pair i bought from breeder for decent price but i d like statt breeding and try to reproduce from 0 to rianbow or atleast some interesting colour i should pair with one since idea is to try buying 1-2 more pairs thanks in advance. I hope to get answer soon if its worth buying this guy before someone else does thanks in advance alot. Also if any good breeder or so that could post few pics of what pair colour to connect to try gettin rainbs tnx
